X128 is a Spectrum 48/128/+2/+2A/+3/Pentagon/Scorpion emulator, originally developed as part of my University Honours project.
For a full description of the emulation features, I recommend you read the latest X128 text file.

V0.94 Improvements: [03/09/02]

• BUGFIX: 16K DISCiPLE ROM would not load properly (it was flipped by 8K).
• BUGFIX: R-register wrong when TR-DOS paged in/out (AnyTank, BBSTOP#4, BBSTOP#5 and anything using "Ars Protection").
• BUGFIX: DAT trap switched off after reset (Elite 3).
• BUGFIX: Sound synchronisation finally fixed!
• BUGFIX: T-states could be wrong after loading a V3 Z80 file. (Audio fix).
• Added INI option to flip 8K for MGT ROMs (in case it's necessary for some).
• ZX81 emulation (half-finished).
• Support for P and 81 tape files (ZX81).
• Support for FDI, FDD, SCL and Hobeta ($?) files.
• TRD files can now be 40S, 40D, 80S or 80D.
• Fuller, DK'Tronics, TrickStick 1 and TrickStick 2 joystick support. (Last 3 only available in "half-finished" mode).
• Kempston joystick can be (optionally) switched off completely (previously it would still leave port 31 reading 0).
• VESA 2 linear video modes supported (partially) - Please read the warning.
• Amiga, AY and AMX Mouse.
• D40/D80 disk interface (half-finished).
• Support for 000 files (builds a D80 disk image).
• IF1 emulation (half-finished).
• BUGFIX: Num-Lock caused Caps Shift to be pressed with 'grey' keys.
• PC Keys used for joystick can be redefined.
• Sinclair Profi+ (half-finished).
• Auto frame skip (replaces /frame 0).
• Speed up key - hold down " ` " (the key to the left of "1") for full speed (works best with auto-frameskip on).
• Long filenames supported under Win'95/98.
• Audio save to VOC or WAV.
• No more relative path problems from the command line (..\A.SLT is fine).
• (Basic) ability to enter POKEs.
• Option to save SCR files in the place where SGD would expect them.

Only the Soundblaster version is updated. I'll do an Adlib version if demand dictates it.

DOWNLOAD SECTION

---

The following files are available for download. Note that X128 v0.93 for DOS requires the DOS/4GW extender, which is supplied separately - if you don't already have it, download and uncompress it to the same directory as X128.

	X128 (DOS/SB SAOM Version) v0.94 (231,433 bytes) This is the SAOM (Special Audio Output Mode) version, which uses the SB to produce excellent quality sound, including the 48K internal speaker and AY speech. If you have quite a fast machine, this is the version for you, but even if not you should try this one first anyway! If you download it and find you can't get it playing the sound well even with frame skipping, you can try the Adlib version below, which is like older versions of X128.
	X128 (DOS/Adlib Version) v0.93 (167,909 bytes, not updated!) Try this version if the above one fails on you. This one is more like the older versions of X128.
	X128 ROMS (204,075 bytes) You need these to run the emulator. Delivered separately since v0.9. If you already copied these earlier, an update package for the v0.94 addition is available too.
	X128 (Unix) v0.5 (121,968 bytes) Note: the Unix/X version is currently not being developed further.
	X128 Source Code v0.5 (58Kb)
	DOS/4GW runtime v1.97 (143,699 bytes, not needed for v0.94)
	SLT Utilities (DOS) v0.61 (28Kb)
