Re: [Req] bin/cue cdimage support

As of commit e0a406, PCem wx-SDL2 fork has supported cue/bin format... Maybe we just need a patch for the mainline PCem.

I just build a 64-bit PCem-wx-SDL2 https://github.com/mborjesson/PCem-wx-SDL2
It seems impossible that a SDL display window and control window can be merged into one window.

Re: Best machine/graphic card/setting for Windows 95 emulati

It might be ATi Mach64. I tried some 2D RPG games on v10.1 before and Mach64 performs better than S3 Trio64. And S3 ViRGE was the poorest.
On v10.1, the blitter isn't in a dedicate thread but on v11 it is. So the 2D games should run faster.

depcomp and missing in your source folder was linked to /usr/share/automake-1.11/depcomp and /usr/share/automake-1.11/missing. but automake-1.11 is an older version.
Go to /usr/share/automake-1.xx then copy depcomp and missing to your source folder.
