V2.2: 15-Dec-2024 by wavemotion-dave
- Fixed paste of filenames allowing more characters (not just A-Z, 0-9)
- Added sound (speech) samples for Microsurgeon.
- Added sound (speech) samples for Fathom.
- Fixed River Rescue (improved VDP interrupt mask handling).
- More games load with better key maps (e.g. Defender now auto-maps X and Y as Hyperspace and Smart Bomb).
- Reverted to allowing both '3' and '9' as the file type modifiers for "inverted cart type". There are examples of both in the wild.
- Main menu cleanup and refactor.
