Last 27th unstable problems.

Zoomglitching seems to be fixed.
KOF 94 MVS/AES flickers so bad, CD version misteriously works perfect.
PAL MODE : The RASTER EFFECT is completely desynced. So sure that almost nobody plays in PAL, but it didn't happen in the 19th unstable.

Things like the staff roll in AOF 3 seems to be related to UNIBIOS and certain cheats enabled. It can be an UNIBIOS problem, and not the core. Needing confirmation from real hardware.

please provide testing instructions

I've tried KOF94 and didn't find abnormal flickering. Although i'm not familiar with this game. Where it flickers?

For KoF94, the flickering is present at the end of each battle on the text. It flickers on the right part of the text.

Text flickering might be caused by Universe Bios. Try original bios.

The raster effect is broken on the first stage of World Heroes 2 Jet in pal mode. I'll check out the timer

Text flickering might be caused by Universe Bios. Try original bios.

I use only original bios. Cheking with the last commit 7ba6bce build with autobuild it is still present with original bios.

I link the previous issue related to KoF 94 maybe it could help to see at which commit it was previously fixed in the past

Flickering in KOF 94 can be saw immediately in the HOW TO PLAY screen. Ryo Sakazaki sprite is not stable. From Right to left, pieces of sprites here and there. The flickering of texts is a consequence of this too.

This problem was solved in different builds in the past. Sprite flickering in KOF 94 is a problem that exists too when using NEOSD in a real NEOGEO or using 151 in 1 bootleg carts ( with original cartridges it never happens). Usually this is solved by reseting the game 2, 3 times in the original AES console. In MiSTer it CAN'T be fixed by reset.... So hope this can help to fix that annoying issue.

Thanks guys !

If it also happens with bootleg carts then it points to rom speed issue.

Try adding rom_wait="1" to kof94 in romsets.xml same as with ninja commando here:

NeoGeo_MiSTer/releases/romsets.xml

Line 115 in 7ba6bce

    
           <romset name="ncommand" pcm="1" altname="Ninja Commando" publisher="Alpha Denshi Co." year="1992" rom_wait="1"/>

It fixed the glitches for me.

testing KOF94 with the new romset.xml it is working great with darksoft rom thank you :)

Rasters and KOF 94 Fixed !

If everything from OP is fixed then please close the issue. AOF3 has separate opened issue
