@Redguy

Played Yoshis island yesterday. Had a graphics issue on first try but after power cycling the snes, works perfectly. Saves an all.

My life is complete.

Thank you again for your hard work

Give this version a try.  I fixed the doom graphics glitch bug which may have also fixed stunt race fx and the startup crash.  You can turn the in-game hooks back on, but they are now temporarily disabled in gsu games.  I still need to fix that bug.

Fixed doom graphical glitch.
Fixed in-game hooks by temporarily disabling with gsu games.
Fixed save problem with non-gsu games.

In-game hooks are still not perfect even on stock SD2SNES firmware, so just let the guy fix the core first, or get it running as best he can before we start worrying or moaning about in-game hooks.

i not understand the problem with the in game hook ?

It causes glitches in some games. It's disabled for SuperFX games for the time being until the core is more stable and bugs are fixed.

A little post to give you all my congratulations for your work.
Last time we had so much hype in SNES sphere was when the SNES-CD was discovered.
Do you realize how much hope you give to the SNES community
Nice to see people with such gift.

now, the question is... will it be your only project... ?

redguy you are a god among men. never thought I'd be able to play Star Fox 2 on real hardware, but here it is.

[Relikk]

ok thanks for the infos but option  in game hook is activated for the normal game or completely disabled for all games or just disabled for super fx game ?

It acts as normal with other games, and is only disabled for SuperFX, yes.

Fixed save problem with non-gsu games.

Does this mean that non-gsu games don't need to be reset anymore to save? Meaning, they will write the SRAM like normal while you are playing a non-gsu game?

Seems as though the Star Fox 2 ROM from the SNES Mini Classic doesn't work. Black screen.

The file "fpga_base.bit" is the same in the original firmware and in the GSU V01 and V02.

Will always be the same?

It did for me. Disable in-game hooks. And power cycle the system if it's not working. It may not work the first time (which happened to me).

Redguy, I think the tag for the latest pre-release points to the wrong commit. Not a huge problem, but just something I thought I'd let you know about.
