Lo primero de todo, para el dracula X hace falta un EZ3.
Sobre como usarlo te remito al txt que acompaña al emulador donde explica como usar los juegos de cd:
Using CD-ROM with PCEAdvance:
--------------------------------------------------------------------------------
To be able to use PC-Engine/TurboGrafx16 CD-ROM games you have to have a CD-ROM System rom in your build.
Use the normal builder to add any normal games that you want but also add a CD-ROM System rom to the compilation. After that also add the datatracks from the CD and optionaly a .tcd file ("cue" file) to the compilation, this is easiest done from a command prompt or in a batch file:
copy /b pcebuild.gba+cdgame.tcd+cdgame.iso pcecdbuild.gba
The .tcd files are not needed for all games, but the games that have several datatracks require it (not the ones that have a second copy of the first datatrack on the last datatrack), I will try to make .tcd files for all games that are requested. You can only have 1 CD game in each build right now and you start it by choosing the CD-ROM System and then pushing start.
To use it from Pogoshell just make a build with only the CD-ROM System rom and use it as the plugin for iso files (and pce files).
