Support for SDD1 games - Githubissues

GoogleCodeExporter commented 8 years ago

I've tried to emulate the game "Street Fighter Alpha 2", which uses an 
enhacement chip called SDD1 
(http://en.wikipedia.org/wiki/List_of_Super_NES_enhancement_chips#S-DD1) on my 
RPi with null result.
Apparently, Snes9x v1.39 is capable of running these games if you put two files 
in the freeze directory. I've assumed that the freeze directory is the same as 
the snapshot directory (at least is the same in the Windows version). The 
result of the emulation is a black screen, you can exit, save states, etc. but 
no game at all. This works perfectly in the Windows version.
I've also tried to put these files in the ROM directory with the same null 
result.
As I've read, this problem is solved in the Dingoo version, but I don't know if 
the pisnes port supports this enhacement chip

If you need information about this, these are the posts I've read about:

Also, it would be nice to know what enhacement chips are supported

I think there's only two games that use the SDD1 chip, and it would be a lot of 
work to get that working for just those. I did have a quick look  to see if it 
was possible but it turned out to be a lot of work. So currently I have no 
plans to support it - but I may have another look if I get some time. Thanks 
for the links, they are useful.

I believe it supports all except SDD1 and FX games.

There are only two games that uses SDD1: "Street fighter alpha 2" and "Star 
Ocean". 

You might delete or modify changes.txt file. The first point of the file says 
it can emulate that chip (I guess you used the linux version and you didn't 
noticed)

Thanks for the attention
