đ¯ Priority Testing Targets
We appreciate testers putting stress on these specialized emulation subsystems.
Test titles utilizing custom fastloader routines (Action Replay, Epyx FastLoad, Hypra-Load, JiffyDOS serial bus handshake).
Multi-disk adventures on 1571/1581, CMD FD-2000 disk images, and SD2IEC host filesystem directory structures.
High-resonance filter sweeps, combined waveform playback, and multi-SID stereo tunes in famous C64 chiptune releases.
Verify that rapid live rewinds preserve flawless cycle synchronization across CPU, VIC-II, SID, and CIA timer state.
Test booting homebrew and commercial games purely on built-in SoftKernal with Simons' BASIC / TSB extensions.
Test 20MHz SuperCPU speed scaling (WDC 65816) and Zilog Z80 CP/M cartridge system software.
