I'm unable to test that because the 1MB/4MB RAM portion of my Action Replay cart no longer works with any of my Saturns. I'm guessing that the address pins for RAM access can't be read; if true, that's not surprising since the cart is in so-so condition.@privateye : can you please try to load X-Men vs Street Fighter -> soft reset -> load Samurai Spirits Amakusa Kourin and see if graphics are corrupted or not ? If this problem can be reproduced I shall then prepare a beta build to check the status of A-Bus access registers.
It's important to note that these 1MB games have corrupt graphics when using an Action Replay*¹ or official 4MB RAM cart:
- King of Fighters '96 *²
- Real Bout Fatal Fury (not the special edition)
- Samurai Shodown IV
(*2) 4MB hack is available and includes new features not found in the vanilla version (e.g. faster loading times, bosses already unlocked).
In most cases, loading Samurai Shodown IV (Amakusa Kourin) with an Action Replay cart will result in corrupt graphics, regardless of what game(s) you have (or have not) loaded beforehand.
Do you confirm that these games have no graphical corruption when loaded straight away from cold boot? As I mentioned above, it's normal for these to have graphical corruption on official 4MB RAM carts and (most) Action Replays.The games that only support 1MB, like KOF '96 and Real Bout will have graphical corruption if a game like Vampire Savior has been run beforehand.
