I really wish this one would work on the Polymega. This patch slows the game to a crawl on that console.

This is the best hack ever made for Super Nintendo! The idea of making snes KI2 is epic! I am the youtube user "retromagico" and posted a comparison between the original Snes Version vs the Arcade Mega Patch... Have you thought about implementing a support chip such as SA-1 or Super-FX to run the 3D scenarios and that could be compatible with an original SuperNes (with everdrive)?

EDIT: I'm sorry! I just read that you posted the reasons why you don't use a support chip in the game (because of the change from HI-ROM to LO-ROM or something like that). Anyway you've done an epic job!
And if I could help with anything, (although I don't know programming), I am available to assist you in any way I can!

Now i can use support chip. I'm working on KI2 and i use decompiled code with DiztinGUIsh this time. Clean code, without messy subroutines in empty space and spaghetti code. Disabled KI1 codes in order to gain space for KI2 codes.

There is a huge problem with extra chips:*
Even that you can have 3d backgrounds to work, there is an unsolved problem with sprites: You can make them smaller, you cannot make them huge when they are close to screen. And you cannot skip this.
One cheap solution is to force an extra chip use one Bg layer only for sprites, but you will have low fps on vram DMA.


*I was wrong. KI2 would not rotate the stages in that way that sprites would be close to camera, such as KI1. So technicaly you can have scaling, WITHOUT special chip. I have something in mind.

WOW!!! That's a huge and great notice!

It would help a lot if the original KI2 rom for SNES, which was never released, was leaked.

I get it... The VRAM on the SNES is also too small to handle everything... right?

The solution you propose, (which would not work), be similar to the used for the 2D scenarios in the original arcade?

No. Writing it from scratch will be better.

No it's not the case. Vram size is ok.

No arcade renders different.

Have you thought about also making a Mortal Kombat Arcade edition just like the Sega Genesis version? I guess in that case you have to modify almost everything.

In case it helps you... I have a super nintendo with an everdrive, and I do audio, video and graphics editing (sorry for my bad English, I'm using Google Translate to write as best as possible)

No Mortal Kombat, it would take years since i only have 1 free hour per day. Also KI is more impressive on snes than Mortal kombat. But i was thinking about SSF2T because till today is in demand and snes can have the best console version.

Coincidence, i also do audio video and graphics editing and also don't speak English.

AWESOME!
It would be very interesting to see an SSF2T like the arcade! (however I think it would not surpass the epic task of converting KI2 to the Snes).

Where you from dude? I'm a hardware technician and architect (of construction, not programs) and from Argentina... I have a healthy envy of your programming skills!
