new test https://mega.nz/file/TcxmCYpQ#xMgXa8i2o ... Ju84WQgkXs

Testing.

So far so good, it entered attract mode without problems. Will play it throughout the day and report back.

Thanks for the hard work!

I hope now it will work, in any case, my freezes are gone
if everything goes well, I will try to put these fixes into Blue Dolphin

Are these ram alloc hacks? Also great work as always

The main code is changed, maybe I will also follow to modify mine

Maybe you should link the fix in the first post (or update the download folder)? Just to get people testing the newest version and not the old one.

Excited to see if this also works for Dolphin Blue!

The main code is changed, maybe I will also follow to modify mine

added function DMA_abort, look DMA_abort_real

Thanks, add this code in the next game
Hope the previously released games will not freeze

Do you think this could also be used for kofxi / ngbc?

gdemu clone With the latest fix test. The game works fine on 3 stages, but has the same problem since stage 4 when I do the super move (as I mentioned before), freeze and repeating the character's voice

try to make a save state in demul if you can, when to execute and show the bug. the performance/bugs should be the exact same as the ones on real hardware to make it easy to fix.
