SpeccySE v2.1 is released. SpeccySE is a ZX Spectrum 48K / 128K Emulator for the DS/DSi. To run requires one or both of the original ZX Spectrum BIOS ROMs. Place 48.ROM and 128.ROM (exactly so named) into the same directory as the emulator or else in /roms/bios or /data/bios

SpeccySE Changelog:
Version 2.1 - 30-July-2026 by wavemotion-dave
Optimization pass on beeper driver so games sound a bit more authentic with fewer buffer drops.
Optimization pass on CPU and ULA driver to eek out another 3% speed.
Pressing START/SELECT will stop tape load and return to normal play mode.
Improved key handling for SHIFT and SYMBOL when mapped to one of the NDS buttons.
Now allow the 128.rom to be split as 128-0.rom and 128.1.rom as is often found when searching.
A few more games added to the tweaks database so they run and look correct (Gauntlet, Darius+, etc)
Minor improvement for the undocumented flags handling for improved accuracy.
