Hi
Have you been though these extra config steps?
Installed winuae?
Got the kickstart roms and setup winuae to point to these om dirs. (There used to be a dat file for the roms - could look it out if needed).
(From winuae - Settngs, path, "rescan roms". You need
A500 Boot rom 1.2
A500 Boot rom 1.3
a600
a1200 - maybe where ever you got the install already has these?)
It sounds like gamebase is nearly setup - just need some extra config :-
Start gamebase and load in gbamga 1.6 - GEMUS menu - click the enry for relavent "x-arcade". On the emulator path\filename -click the browse and select the winuea.exe location (using c:\program files\winuae\winuae.exe)
You can also click GEMUS / manage emulator - and move the x-arcade to the top one. (When you left-click "play game" - it will lauch the top listed emulator. Rigt click brings the se;ection)
If your got the deli-player - then click tools \ options \ music players \ select dli - click the "sqaue box" and selec the "player path\filename".
If your using a new version of winuae - then theres a error in the script which needs modification as listed n the bottom post here :-
