Issues ROM version 4c
kervinck opened this issue · comments
- romType variable is still at 0xf8
- Hitting [Start] (or PgUp, Ctrl-Alt-Del) momentarily corrupts the VGA signal
- Arrow in main menu looks a bit misaligned
- Keyboard response in Easter egg is sluggish due to continuous cursor drawing. Maybe this can improve by redrawing only when it changes.
- Sound table becomes visible at first activation of Munching6502. Maybe clear screen first.
- Replace Bella with Chuck
- Consider alternative magic value for MODE -1
- Add message to start of A1 mockup (need to win ROM space first)
- SYS_SpiExchangeBytes_130 is functional but induces a VGA timing error
- It's better to clear channelMask at boot time, and only set it in MainMenu.gcl (better for ROM applications that don't need MainMenu)
- There's 1K of unused space, we can shoehorn the A1 disassembler in that. Maybe also asm.
- $FFDC PRBYTE can crash on invalid chars, unlike the A1 version
--> Doesn't seem to be the case
- The blinkenlight sequence appears to have a hickup during cold start
--> Doesn't seem to be the case
- Apple1.gcl doesn't need to clear channelMask as well
- Disassembler: We can restore the removed '-' after the address, because now that we're returning through GETLINE instead of RESET, there's no more unwanted '\' symbol that can spoil a line.
- Disassembler: ROR patch still must be applied (this code is REALLY vintage)
- Support loading of Microchess.gt1. Solved with dc903c1
