Dragon Force 2 : invisible and non killable units bug #166

Open lilo-san opened 4 years ago

lilo-san commented 4 years ago

OS: Windows 10 Retroarch Version: 1.8.8

Some troops are invisible and can't be killed. This happens at random like 1 or 2 troops on each side, but the more troops, the more it happens. Almost all battles will ends in a draw forcing the player to repeat the fight.

NOTE: This bug seems to also happen in other emulators: https://www.reddit.com/r/SegaSaturn/comments/5u5e0j/dragon_force_2_buggy_or_just_me/

NOTE: The Kronos core doesn't seem to have this issue.

This has been an emulation issue with Dragon Force II since SSF. Mednafen had this issue as well for a while as posted here https://forum.fobby.net/index.php?t=msg&th=1357&prevloaded=1&&start=80 . However it was fixed with 1.23.0. as posted here https://forum.fobby.net/index.php?t=msg&th=1357&start=0& . The current stable version of Mednafen is 1.24.3. Retroarch is unfortunately using an older version of Mednafen 1.22.2 for its Saturn Beetle core where the bug is still present. So it's not really an issue with Retroarch itself, we just need the Saturn Beetle core updated.
