For example, being able to right click on a game and select a secondary executable to run the rom would be a cool future addition.
EL already have that... it's called AlterMAME. You can select a second MAME binary to play MAME games.
Go to Emulators Setup screen and select this special MAME compile in the AlterMAME slot (MAME tab).
Then, when you want to play those Votrax games, just load it with AlterMAME (mouse right click, select "Play With AlterMAME"... or just use the "Shift+ENTER" hotkey. No need to hack your way with HBMAME.
See attached pic...
After going through some of your update posts again, it looks like you may already be on the case in a future update.
I'm porting EmuCon frontend features into Emu Loader... but MAME software lists will NOT be part of the console/computer systems. They are handled as MAME non-arcade games.
But you won't be able to run arcade games with these console/computer emulators.
