If your looking for the Modeler team's sound emulator frontends use the links below to download the newest versions.
M1 Launcher release 2 for M1 version 0.5
GXP Launcher for GXP version
I (that's me, MrClick) have not produced the M1 and GXP
programs themselves. That credit goes to R.Belmont and the Modeler team.
So if you have questions about M1 or GXP then the forums at impactemu.com.
And don't ask me or anyone in that forum for ROMs of any kind. Read the rules and for god's sake don't be a muppet.
