V4.7 : 11-May-2024 by wavemotion-dave

  • X and Y buttons now shift the screen down/up by 16 pixels so you can position the score off-screen and use these to pan up/down to see it.
  • Fix for Supercarts so that they start in bank 0 (Legend of Silverpeak should now load)
  • Internal database tweaks for the latest homebrews and ports.
  • Other minor tweaks and improvements as time permitted.

V4.6 : 06-May-2024 by wavemotion-dave

  • Each game that utilizes a High Score Cart (HSC) gets its own 2K .hsc file
  • Improved High Score Cart (HSC) emulation - improved initialization of the SRAM contents.
  • Sanity checks added so that carts marked as 'NORMAL' (or selected as such) but are larger than 48K will not corrupt memory.
  • New magnifying glass icon to ZOOM (and center) the display 1:1 with real 7800 output. This will crop on a DS/DSi since it only has 256x192 but very useful to toggle the 1:1 zoom for High Score Entries, etc.
  • Support for .a78 V4 headers (will fall back to V3 if not available)

V4.4 : 14-Nov-2022 by wavemotion-dave

  • New palette options from the Trebor 'Pro Pack' of colors. COOL, WARM (default), and HOT allow you to shift the color temperature slightly on a per-game basis.
  • Improved sound channel mixing so as not to halve the volume when mixing POKEY + TIA.

V4.3 : 11-Nov-2022 by wavemotion-dave

  • Full support for the new Banksets scheme including the upcoming Attack of the Petscii Robots game!
  • Added the stable "illegal" opcode support for the 6502 CPU to ensure all games run properly.
  • New Maria cycle handling is more accurate than it's been in any previous version. More games run closer to perfect.
  • Improved rendering and a bit more optmization to make almost every game playable on the older DS-Lite.

V4.2 : 06-Nov-2022 by wavemotion-dave

  • Added support for bankswitched RAM (32K of RAM switched in 16K chunks). This makes the Ex version of 1942 playable.
  • Added alternate way of handling bankswitched RAM the same way as the DragonFly cart or SN board: via writes to 0xFFFF.
  • Fix graphical glitch for Ballblazer (just hiding it off screen).
  • Numerous small updates to the internal cart database to ensure game run with the proper settings (mostly High Scores)
  • New 8x density on the High Score Cart - transparent to the user but provides more slots so the HSC won't fill up.
  • Flat 32K plus RAM cart type supported.
  • Pokey @800 supported for upcoming homebrews.

V3.9 : 29-Oct-2022 by wavemotion-dave

  • More optmization and more games playable on the DS-Lite.

  • Fix for One-on-One.
  • Fix for voices in Jinx.
  • Cleanup of code - removed unused functions and vars. Switched to a memory-lite sprintf().

  • Removed most of the old hacks for DS-Lite as the speed is good enough to render those games properly.
