V6.6: 07-Apr-2022 by wavemotion-dave
- CAS icon implemented to provide a menu of cassette-based actions including swapping tape/disk for multi-load games.
- SC-3000 emulated more fully with support for the SC-3000 Survivors Multi-Cart.
- 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.
- Better overall memory handling to keep the program size manageable.
