SpeccySE v1.6 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:
Revamped Z80 CPU core to provide more accurate timing and memory contention/floating bus. Multi-color games (aka Nirvana+, BiFrost, etc) now play and look reasonably correct and CPU speed is generally correct.
Fix for AY music not restoring properly on some Load States.
Smoother beeper sound for improved fidelity.
Added Kempston 2nd Fire button which can be mapped in.
Default machine is now the ZX Spectrum 128K but it will revert to 48K for common games with compatibility issues.
Other minor cleanups and improvements as time permitted.
