Exile bugs out (pun intended) when killing ants in the first action area. #67

Tested with a TruRip verified ISO (no Redump available for the US version). This problem occurs on both beetle-pce-fast and beetle-supergrafx, as well as on standalone mednafen when using pce_fast module. It plays correctly when using the standard pce module on mednafen. This was tested on both a Raspberry Pi 3 running RetroPie 4.2 and on Windows 10 running Mednafen 0.9.46, both using a syscard3.pce bios with the correct md5 checksum.

Here is a video I captured of how to replicate the bug (the exact moment it happens is at 2:07 and onwards): https://www.twitch.tv/videos/166253912

timing issue. if you kill them from above them, these bugs wont bug out...

is there a problem moving forward with the game aside from these?

ghost commented 6 years ago

Invincible ants still happen with latest builds of pce-fast and supergrafx on pi and pc via retroarch.

ghost commented 4 years ago

Yes, I have seen that issue as well on the RPi4 and PC builds.

darksaviorx commented 4 years ago

The issue doesn't exist on the accurate version, and the pi4 can run it at fullspeed, so I'll use that.

@ghost the linux version worked, but core is rather old at this point. can you update based on latest commit? both pce_fast and supergrafx cores?
