 -----------------------
 This emulator will support .cas files for the Spectravideo SV-328 (64K machine). You can use the START and SELECT buttons for the common bload and run commands.
 
+Sega SC-3000 Compatibility :
+-----------------------
+This emulator supports .sc files as ROM only (not cassettes) but ColecoDS will support the amazing SC-3000 Survivors Multi-Cart and MEGA-Cart. Strongly prefer the Multi-Cart as it's smaller and contains the same selection of tape games. Just rename the 2MB or 4MB binary as .sc to load in ColecoDS.

 Controllers :
 -----------------------
 You can map buttons to either P1 or P2 controllers.

+* PAL vs NTSC now supported for the Memotech MTX, Spectravideo SVI and SC-3000.
+* SAV files have been streamlined and are now smaller/faster. Old saves won't work. Sorry.
