SpeccySE v1.7a

SpeccySE v1.7a 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:
Implemented Favorites system - use SELECT in game selection screen to toggle Like/Love.
Massive overhaul to provide smoother double-buffered frame rendering on all hardware (DS-Lite/Phat users rejoice!).
Improved beeper audio handling to smooth out sound in some games - especially improved on DSi hardware with the faster CPU.
New Frameskip option added for DS-Lite/Phat. Default is to render 3/4 frames to get enough speed for all games but many games can run without frameskip. DSi always renders all frames.
Synchronized the DS/DSi vSYNC to 50Hz to match the PAL emulation for smoother tear-free experience (any tearing remaining would be present in the game itself).
Properly cap at max volume for the games that utilize both the 128K AY chip and the beeper (was causing crackling sounds).
Fixed Arcadia input so the ship doesn't jitter across the bottom of the screen.
Added more undocumented Z80 opcodes to fix Nothing (that's the name of a game!).
Illegal ED opcodes now act like nop-nop and consume 8 CPU cycles as they should.
Improved Tape Position menu now shows current tape block to aid in positioning the tape for some multi-load games.
Added Z80 7MHz Turbo Mode for the few games that take advantage of it (e.g Nothing). Note the DS-Lite/Phat don't have enough CPU processing power to render at this turbo rate.
About 15% improvement in performance - mostly to help out on the DS-Lite/Phat render even the most complex games smoothly.
Version 1.7a hotfix to correct a CPU optimization bug that was causing a few games to crash (e.g. Rainbow Islands)
