Multiple games (Capcom + Astal) // REGRESSION - Doesn't boot anymore after the SEGA logo since SMPC changes #117

After some tests with Kuba-J, we have found a regression on Tenchi wo Kurau II - Sekiheki no Tatakai (Japan).

The last working version was core version 20240204. The changes committed on 2024-02-06 on the SMPC broke the support of the game.

No change on core 20240210, even after some changes for fixing regressions.

Zet-sensei commented 4 months ago

I can fix the regression by injecting the SMPC code from 20240202 version (before the changes + adding just the delay for the INTBACK command) to the 20240210 version of the core.

Zet-sensei commented 4 months ago

The new core version 20240212 didn't fix the problem.

EDIT :

Night Warriors - Darkstalkers (USA);
Vampire Savior (Japan) & Vampire Hunter - Darkstalkers' Revenge (Japan);
Cyberbots (Japan) are impacted by the same regression so far.

Astal (USA) is also impacted by the regression.

Zet-sensei commented 4 months ago

Fixed with core version 20240215.
