SourMesen 918379b7a7 Debugger: Tilemap viewer - Added option to pick background color (#238) 
Also, minor bug fixes for WS:
-Fixed tilemap viewer for sometimes using the wrong background color
-Fixed the 4-bit RGB color values in the palette viewer having the R and B values swapped

SourMesen d76660c481 NES: Fixed BG/Sprite shifter edge cases (#190) 
-Fixed BG shifter reload timing by moving it to the last dot of every 8-dot sequence (instead of the first dot). Fixes the "BG Serial In" test.
-Changed sprite shifter init/reset logic to allow edge cases where the shifter starts outputting pixels on a different scanline (when rendering was disabled during specific portions of the scanline, etc). Fixes the "Stale Sprite Shift Regs" test.
-Tweaked code in ProcessScanlineImpl, etc. to slightly improve performance
-Fixed missing PPU register mirror reads/writes in event viewer

SourMesen 4b8669d34b Debugger: Tilemap viewer - Fixed "edit tile" behavior on SNES when the tilemap is using 16x16 (or 16x8) tiles (#72) 
Also, added support for horizontal/vertical mirroring when editing the mirrored tiles from the tilemap.

SourMesen 8e4dd329ac Debugger: Lua - Added new APIs: getCpuState, setCpuState, getMasterClock, getCpuCycleCount (#58) 
getCpuState/setCpuState allow the same functionality as getState/setState, but limited to only the CPU's state, making them much faster (some performance optimizations to the serialization & Lua code were also done)
getMasterClock/getCpuCycleCount are very fast alternatives to getState when all the script needs is a cycle count.

Sour 762e5ea617 Debugger: NES header editor - Fixed incorrect values for VS system roms 2025-02-11 21:46:30 +09:00
Sour 031cb7058c Debugger: Fixed issues with NES/SNES/PCE assemblers 
-Labels defined within the assembler that were referred to before their definition did not work properly and ended up being assigned the wrong value (when the label's address wasn't a value between 0x100 and 0xFFFF) - this is fixed by running multiple passes until the resulting byte code stops changing.
-Fixed issues where e.g EOR $00, Y would be assembled as a 2-byte instruction, which is invalid.
