Here's whats new: 03/11/2001 v0.500 'General Sound roxx the emuscene!' !WARNING! CURRENT SETTINGS FOR THIS VERSION REQUIRE P300+! !P300 IS NEEDED FOR LOW-LEVEL GENERAL SOUND EMULATION ! !IF YOU HAVE SLOW PC OR DONT WANT GS - SET GS=NO in cfg ! - New : low-level emulation of General Sound! General Sound is an add-on board for hardware MOD and sound FXs playing. Powered by Z80 cpu at 12Mhz it has 4 audio channels (8bit for data + 6bits for volume for each channel), 128 or 512Kb of memory,32Kb ROM. Apart from playing audio its cpu can be used for other tasks (code can be uploaded to GS & executed). 4 switches in cfg: GS=YES|NO - YES to allow General Sound emulation GSMEM=128|512|1024|2048 - choose how much RAM General Sound has GSHLE=YES|NO - choose NO for low-level GS emulation (requires fast CPU - P300+) GSRESET=YES|NO - F12 resets GS with Speccy - New : Debugger for General Sound (use End key) - New : Procedures reading&analyzing config files was rewritten. If you have any problems with cfg files - simply try the ones which come with z80s_500.zip - New : Digital sound buffer for AY-LPT!!! (Doesnt work correctly under Winsuxx at freq>1000 Hz). There are lot of new options in cfg-file, be careful! REAL_AY=YES|NO - use real AY instead of internal emulation; AY_DATA=0-FFFF - address of real AY data port AY_RESET_SIGNAL=00000000 - binary form of AY RESET signal AY_RESET_MASK=00000100 - binary mask of RESET (bit 2 for LPT AY) DIGITAL_SOUND_BUFFER=YES - Enable Digital sound buffer Find more info about the real AY in cfg file! - New : Added 8 new timing schemes for VMODE=253 (first test) M253_TIMING=0..8 Timing| VFREQ | | (Hz) | ------+-------+ 0 | 78 | 1 | 99 | 2 | 99 | 3 | 50 | 4 | 150 | 5 | 100 | 6 | 100 | 7 | 150 | 8 | 50 | ------+-------+ - New : Rewrote all procedures working with memory. This version uses memory much more efficiently than previous - as a result emulator loads really fast on 16megs PCs. - New : Ability to step over opcodes in debugger. Use F8. - New : Built-in boot for any TRDOS disk. Use PageUp key. - New : Support for VOC and WAV (with images of tape) files added To start playing them use Home key. - New : New submenu 'Browse tape' (in F1 menu). Used to browse tape files, choose start point of playback. Currently works for VOC/WAV. - New : Added a little trick to produce PSG files w/o loggin writes to FE/FF AY regs (Stellar Count demo) - New : Rewrote some parts of Z80 core - should be a bit faster now - Bugfix: fixed stupid bug in TAP loading routines - a lot of TAPs are working correctly now. - Bugfix: ZASM 3.10 reported that no disk is inserted - Bugfix: fixed bug with long file names & browser You can try it now in the Sinclair Spectrum/QL Emulators area.
