Elevator Action Arcade Core - Update!

Got around today to a fix for R3 and a new R6 core . I felt bad about releasing the R3 core without an R6 version, especially since there was a fairly major glitch in the sprite system. I promised I’d come back and fix it eventually, and today I think I finally got around to it but I need some confirmation from the community first.

Cause: The line-buffer address counters could be asynchronously cleared/loaded at unstable times, causing stale or misplaced sprite pixels, this was fixed by making the OD_L1/OD_L2 counters for the line buffers synchronous to the 6 MHz pixel clock.

Update can be downloaded here for those who want to test: https://discord.com/channels/719326990221574164/1547470402543161365

I will add a second button to the control method for jump. Currently, the mechanism uses a configurable delay timer via a single fire button which may not suit everyone

Thimbleweed Park on MEGA65 - work in progress.

• Native C++23 engine on llvm-mos
  
• Rooms in NCM or FCM depending on size and number of layers
  
• Parallax via Raster Rewrite Buffer. First (and currently only) room draws 25 layers at four rates.
  
• Actors on hardware sprites, sorted against RRB layers.
  
• DMA audio, 4 channels, samples stream HyperRAM -> chip RAM as they play.
  
• Art streaming: glyphs in HyperRAM, bands come down as camera moves (large rooms outgrow chip RAM).
  
• Original's Squirrel scripts run on the mega65
  
• Assets built from original game data (GOG or DVD)
  
• Experimental banked SDK: 24 KB banks at $2000-$7FFF, only 20 KB resident. Upstreaming in progress.

🖥️ QL4M65 V1.5 — Sinclair QL for MEGA65

New: QXL.WIN hard disk support (win1_, read and write) and up to 4 MB of RAM, now living in the MEGA65's SDRAM chip. (💡 Keep .win images to 4-8 MB)

⚠️ R6 only. The R3 has no SDRAM chip — that's what makes this possible. R3 owners: stay on V1.01, still available and still the best build for that board.

Built on MJoergen's SDRAM controller. QL-SD driver by Wolfgang Lenerz and Marcel Kilgus.
