Classic99 - v382
If this software is cool or useful to you, consider a small donation to the programmer!
There is *no* need to pay to download and enjoy this software!
But it's a lot of work and I do it in my so-called spare time, so a couple of dollars
would be really appreciated! :)|

Classic99 is a freeware TI-99/4A emulator for Windows 2000 and up. Classic99 runs most stuff fine:
-System ROMs and many cartridges are INCLUDED under license from Texas Instruments
-boots and runs all console OS functions (except cassette I/O) and TI BASIC correctly
-most modules seem to work fine
-XB/Atarisoft/Jon379/SuperSpace cartridge bank switching supported
-full sound emulation of all channels including digitized sound support
-Speech implemented for both speech ROMs and external speak
-keyboard CRU scanning implemented
-9901 timer supported
-disk supports V9T9 files, TIFILES/Xmodem files, Windows native files, V9T9 DSK and PC99 DSK images (DSK images are read-only)
-DirectX Windowed and FullScreen, as well as non-DirectX windowed modes.
-Full Sprite collision detection (by pattern)
-Numerous video filter options (HQ4X, 2xSAI, SuperEagle, NTSC, etc)
-Integrated debugger with single step
-PS/2 keyboard emulation built-in
-Mouse-driven menu selection (double-click on screen)
-1MB Super AMS card supported
-Full source code included
TI-99/4(A) ROMs ARE INCLUDED!. Just select the system you want from the menu! This program will likely always be BETA and therefore incomplete.

Updated RXB to RXB2015E and added support folderAdded Harry Wilhelm's Playground, XB256, XB256 Compiler and Missing Link 2.0, and documentationAdded USCD Pascal disks for pCode emulationReworked Clipboard support for Unicode - no longer need 'enhanced' hackFixed debugger VDP memory view to properly work with F18A extra RAMImproved disk directory sizes (thanks to Lee!)Directory listings now REQUIRE trailing period (like TI disk controller)Fix debugger run-away that would break a run if the program breakpointed on an interrupt handler before LIMI 0tweak LOAD interrupt processingCycle counting overhaul - all opcodes reverified and documentedCycle counting on memory accesses revised.possible hang on reset during speech fixedChanged name of 'X' flag to 'XOP' flag (it was confusing me)made reset use the general interrupt trigger functionStopIdle properly place in interrupt handler (not used yet)changed DIV to use a likely algorithm that produces timing results in the correct rangeremoved hack in LDCR and STCR that was setting /no/ flags for word operationsadded Read-before-write to the only four opcodes that have an unnecessary one: MOV, MOVB, CLR and SETO
safer and more correct triggering of the LOAD interruptFix Day of Week from clock to be 0-6 - CorComp manual lied ;)FIAD disks search entire index sector to work around one form of copy protection (Still technically not the same as TICC, and may fail in particular cases)TICC now supports DSK.DISKNAME.FILENAME (not tested on disks other than DSK1)removed old bigfilehack filenames and implemented address register read and write (Read untested)Allow high ascii as a terminator in filenamesFix directory listings that return errorsWrite the Disk DSR buffer header to VRAM. This makes P-Code work with the Classic99 DSR.Fix VDP disk buffer header for Corrupt DSK RAM optionfix EOF flagfix off-by-one in header of variable length FIAD files for bytes in last sector
Undo previous disk hack unhacking - it wasn't a hack ;)disable jitter buffer debug (haven't worked on that for years)fix record counting - fixed vs variable, rather than relative vs sequential.clock can now be opened in INPUT mode (oversight ;) )
Fix filename padding in directory for ImageDisk and FiadDiskadd warning on pCode that the Editor doesn't like overdriveFix record index handling for sequential filesmakecart tool now supports dumping cart space as an 8k cartenable writes from TI disk controllerremove non-inverted bank switch hacksupdate TurboForth to 1.2.1allow loading of up to 32MB of bank switched cartimprove F18A GPU interleave mechanismchanges to disassembler to show GPU instructionsallow display of extra 2k VRAM in VDP debugger
(forgot to post updates for 377)Fixes for DAC with non-standard CPU speedlarge file hack fixescrash fix for loading 378 files larger than max (2MB)Fixes to make big file hack work with files of arbitrary size.
Note: this is a beta release. I'm not done all the improvements yet. Use with care
Video recording may be broken - I've found "Open Broadcaster Software" to work very well though!
Text to Speech apps and other apps that flood the speech synth, ignoring the control bits, do not work (ie: TE2)
DSK image support is mostly read-only
Uninitialized memory detection does not work on AMS RAM
80 column mode does not work with screenshots, AVI recording, filters, or any stretch except DIB
128k mode is very untested and not guaranteed to work - nor is it intended to be improved later
F18A support is very very incomplete
