Ultima III (pc-98) bug #2660

Open pn-classicgame opened 3 years ago

pn-classicgame commented 3 years ago

Ultima III pc-98 (Ultima Collection Japanese version) does not display the screen. The screen is completely dark. However, the music is playing and the game is running. Also, Ultima 2, 4, 5, 6 (pc-98) is running correctly.

Game file 1: U3_UserSystem.fdi (Drive A) Game file 2: U3_Scenario.fdi (Drive B) config: machine=pc98, pc9801, pc9821, jega

According to this version: https://ia800100.us.archive.org/view_archive.php?archive=/22/items/NeoKobe-NecPc-98012017-11-17/PonyCanyon.zip

It is using LIO BIOS functions, which are not yet emulated by DOSBox-X, therefore nothing appears on screen.

Thank you for your answer. I have figured out the cause. It's not a bug, it's just that DOSBox-X doesn't support it yet.
