Here's the next batch of developer diaries - a conversation regarding what the feature set for MVC2 should be.  This ends with a discussion of upres filters, which will lead nicely into the next blog update.

Email chain to be read from bottom-up.  Please note: much more discussion occurs behind the scenes than what appears in this correspondence.  So don't jump to any conclusions about who made what decisions about feature set.  Otherwise, I won't be able to share this stuff to the public!!

Yes, we should consider offering some filtering options.  hq4x is one of several solutions used by the emulation community, but there are others.  Filters can give strange results, so they are not always desired.. And there is a performance impact.  This is something we'll need to discuss with the dev team.

While we're shooting for the native 480p, the option of an upscale with a much better filter than was used in SPF would be nice. When SPF came out, loads of our fans pointed us to HQX4 (www.hiend3d.com/hq4x.html) as something we should have employed.

Is this something we should be considering for MvC2? Obviously, like in most of the newer Sega games we should give users the ability to turn off the effect, but should we provide it as an option if people want to run in 720p?

This is what triggered my thought process (some of those things look beautiful):

I still think we could experiment with changing the camera for widescreen.  In the video, all the user sees is big black borders on the left/right side of the screen.  If this could be in-game background, this would at least look better at 16:9.  Let’s throw this out to Backbone to see if they can reproduce what we did in HD Remix.

We need to have some kind of auto up-res filter for the sprites.  We can do a lot better than what currently exists.

> [Christian wrote] If anything, that youtube video calls out a need for replays

The problem with replays is not the tech behind recording an entire game and allowing users to save it.  The issue is with how the replays are shared.

[Note: this was before Sony announced YouTube video upload support]

Microsoft has a mechanism for attaching a “game clip” to the top N Leaderboard entries.  If that is what we want to do, the problem should be a matter of allowing users to click on a Leaderboard entry to download and view the game clip.  There may be some limitations as to when and where a clip can be viewed due to emulation restrictions.

If we want to allow users to upload and share game clips, then it becomes a bigger deal with the same issues as with map/level sharing in Flock and Plunder.

55 Characters is a pretty good value proposition, especially given that they’re Marvel. No rebalance needed.

Good point about the 16:9 - look at this MvC 2 combo video:

As for Gametap, basically, if we were to use them for a PC version they would take a ROM image and do whatever they do with it (nearly all of our arcade games are already up there working fine in the same manner), but we have contract limitations.

I suspect 16:9 for MvC2 is going to be out of the question because of simply how much vertical jumping there is in the game, but we could noodle on it a bit to see if it makes sense.

Should we think about having rebalance? It could up the profile of the game/value proposition to the consumer. That said, it’s 55 characters, not 17… so maybe that is biting off more than we should really think about.

All -

We’re looking into getting a true quote for an MvC2 port. I would like to get everyone’s feedback on the following planned info… and then we should all have a meeting to discuss.

Targeted platforms:

XBLA

PSN

x No PC - Christian is this already available on GameTap?

Targeted Featureset:

* Online tech - GGPO or HD Remix rewind tech

* New UI

* Remaining online feature-set identical to SSF2THD:

    8 Player tournament

    Quarter matches

    Spectator Mode (4 spectators)

    Headset support

* 16x9 widescreen support (zoom as it functions now)

* More robust stat tracking

* Worldwide rankings and leaderboards

What it WON’T be:

No new art

No new sound effects

No new particle effects

No rebalancing

I still worry about the fact that if we start adding new features (even if it is parity with SSF2HD) then it opens up Pandora’s box [long development time] and we don’t want to have that discussion.

Our goal should be to create an updated version of what many people think is the best 2D fighter without messing with what works.

Thoughts?

Hi Christian,

I guess playing really is believing. After a few rounds of Street Fighter Alpha played internationally via GGPO, a huge surge of interest among the "Game Center.com" crew and [original] MvC2 producer has hit the Tokyo office like a tsunami. The atmosphere has gone from "What the heck is GGPO?" to "Holy crap! This is great! We HAVE to use this!"

Best,

David

Comments are, to say the least… enthused.  The “where is MVC3!?” thread is also SO recurrent on the boards that the new fad is threads about why it will never exist. 

Best,

Thought the community might be interested in some historical information about how the MVC2 project was kicked off.  This first part is related to building the game from the Dreamcast source code.  I may add more info depending on community reaction.

Email chains posted below (read from bottom up).. I've edited only to remove very specific sensitive information:

From: Gary Lake | Sent: Wednesday, June 18, 2008 | Subject: MVC2 Dreamcast source is here

I have received the Dreamcast source code - you can grab from [details removed].

Caveats from Capcom Japan:

This is the Japanese version of the game.  The network code is based on the DC modem and KDDI matching service.  The game also shipped with a different set of locked characters and a purchase system that required points from playing online and in the arcade in order to unlock items.

I already looked this up, full details here - includes info on how to hex edit the save game file to unlock all 56 characters, 7 stages, and level.

Gary-san,

CJ marketing people understood our situation and said they will help us to make this happen.

But, another e-mail regarding the source code request for DC(JP) version came from R&D.

The person who controls all archive is asking specific reason or plan how we utilize DC Japanese source. His questions are;

- He only have Japanese version source code and wondering is it useful to our developer.

- DC(JP) version has linked feature that use DC Visual memory to unlock certain characters and is not in PS2 and Xbox version.

- If developer use the code from DC may cause the issue that certain character could not unlocked.

- Also network component is designed for Modem and sync logics may be outdated.

If you have any idea to explain would be helpful.

Reason such as DC has less bug means more complete game than Xbox version that we plan to use for the base of porting etc.

I understand that DC version is useful or not can not be determined unless our programmer review the code.

Thank you for your help.

Takashi Kubozono

The PS2 and Xbox versions of the game contain bugs and defects that make these versions not as desirable as the Dreamcast and Naomi versions.

We would like to directly compare the arcade source code with the PS2/Xbox to identify differences and fix the bugs.

We would actually prefer the Dreamcast home version of the game - if this is available, arcade source code would not be necessary.

We plan to base the port on the Xbox version of the source.  However, the arcade version would be very helpful to use as reference, and it would aid bug-fixing. There may be reasons to analyze the original arcade code to determine how online networking was added.

The arcade code will be used as reference and encryption will not be needed for the port.  If the Dreamcast source was available, this would be better.

Hi,

I'm sending e-mail back and forth with CJ character rights department to get additional backup for Arcade version etc.

Below is several question came back from CJ and they are saying without additional information, they are not willing to supply Arcade version source backup because of that backup is for Japanese version and they don't have US version backup other than they already supplied.

Questions from character rights department:

- We think that Japanese version data is not needed to port US version since you have US version source code.  Please clarify the reason you need the data.

- We supplied PS2 and Xbox version source backup and porting target is for PS3 and Xbox360 download delivery.

Of above situation we think you should utilize PS2 and Xbox source materials, not necessary have Japanese version.

Comments from Software engineering group:

- We are wondering why you need AC version source code, the project is for consumer platform since the beginning.

- We also afraid that you are not understand the complexity of the difference between Arcade version and console version.

- Why asking AC version instead of DC version? (Kubozono: This caused by some miscommunication, I already answered.)

Addition to above, I mentioned this MVC2 project is important to us and explained we would like to have any available materials regardless the languages.

Christian-san,

At this moment, CJ does not want supply Japanese version backup material.

I can get more backup materials, If CJ satisfied with our answer and plan.

Thank you

From: Gary Lake | Sent: June 03, 2008 | Subject: Naomi arcade port opportunity

Great, thanks for the quick response.  I can explain that the project is Marvel vs Capcom 2 (www.system16.com/hardware.php?id=800&pag...).

The contract we have [details removed] stipulates that this will be a direct port to XBLA and PSN, with all graphics and gameplay remaining the same as the Xbox1 home version.  The main exceptions are that we will be supporting online multiplayer, adding stats tracking, and updating the front-end to MS/Sony standards.

We can provide the source archive for the PS2/Xbox1 version of the game.  This is derived from the original arcade code, but has stubs for some online multiplayer (that was pulled out of the game at the last minute due to support issues).  I have enclosed a specific ‘source review’ NDA, which you’ll need to fill out and send back [details removed]

For online multiplayer, we would want you to use a middleware library that we have licensed - see GGPO technology (ggpo.net/blog/) for details.  It would be great if the additional stats tracking required could be done through the normal Leaderboards/Ranking scoreboards, but if not, we also have a license for GameSpy available.

I don’t think the game side port from Xbox1 will give you much trouble.  We will provide a list of bugs that should be fixed in the original, but this should not be too significant.  The bulk of the busy work will be finding and replacing all menus with TRC/TCR compliant versions, adding Achievements, etc.

I expect the online multiplayer will be the most significant task.  GGPO works very well for hiding latency, but it requires that the game state be known - game responds to joystick input with only 1 frame fixed delay, game state progresses using basic prediction, joystick data is transferred over the net, if there is a mistake in the prediction the game state must be rewound to the last known good frame.

Based on the scope of work, I am looking for a developer that has the following types of experience

- Arcade hardware and/or emulation, particularly Dreamcast/Naomi/Atomiswave

- Reverse engineering skills

- XBLA and PSN game development with good submission track record

- Network multiplayer

I’ll be up front about this - the timeline requires that the game must be on digital store shelves by [details removed] 2009, so I’m cautiously looking for other options.  It would be helpful if you could provide any detail on experience or skills related to the above areas.

Thank you,

  - Gary
