NDS4MiSTer Public Touch Beta — 2026-08-28

This experimental beta adds basic controller-driven touchscreen input while
retaining the compatible video path, FPGA sound, persistent
cartridge saves, selectable screen layouts, and the default 8-pixel screen
gap from the previous public save beta.

What is new

• The controller's right stick selects an absolute DS touchscreen position.
• The remappable Touch action presses and releases the stylus.
• Touch coordinates, pen release, SPI behavior, and direct-boot calibration
  passed focused regressions.
• The exact core in the package passed MiSTer hardware testing.
• Public source and release metadata are available at source commit
  0db5c71.

Installation

Extract the ZIP directly over the root of the MiSTer SD card. After each
MiSTer reboot, run Scripts/NDS_Kickstart.sh, then load NDS_20260828 from
the Console menu and select your own .nds file.

The ARM renderer is deliberately not persistent. NDS Kickstart must be run
once after every MiSTer reboot.

Important limitations

• Engine B is not enabled, so both displayed positions currently show Engine
  A. Touch works, but precise use is difficult when the touchscreen graphics
  are not visible.
• Heavy 3D scenes may slow down, fall behind, or crash.
• Cartridge-access latency can cause late or missing objects and effects.
• Reset can hang; reselect the ROM through Load NDS instead.
• Chrono Trigger has a separate boot failure under investigation.
• NAND saves, save states, Wi-Fi, and microphone support are not implemented.
• The FPS counter measures completed ARM-rendered 3D frame publications, not
  total emulation speed or HDMI refresh rate.

No games, commercial ROMs, BIOS files, personal saves, credentials, or user
data are included.
