Version 2.0 (2020-11-XX)
- Updated source code from Eric Rechlin's Emu48 version 1.62+ that was merged from Christoph Gießelink's Emu48 version 1.63.
- For the HP49/50 port 2, it is now possible to load a new Flash ROM file (It fully replaces the ROM).
- Replaces the haptic feedback switch with a slider to adjust the vibration duration.
- Fix transparency issue (RGB -> BGR).
