Classic99 - v334

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! :) (Alternately, there's my Amazon Wishlist)

Classic99 is a freeware TI-99/4A emulator for Windows 9x. 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 cartridge bank switching supported
-all three music channels emulated through any DirectSound compatible sound card
-noise channel fully emulated, though user-defined repeat rates are not 100% accurate
-Speech implemented for both speech ROMs and external speak
-keyboard CRU scanning implemented
-joystick support
-9901 timer supported
-partial disk support
-DirectX Windowed and FullScreen, as well as non-DirectX windowed modes.
-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
-Open Source and 100% free

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. I can't provide support with getting ROMs to work - that's your concern. ;)

Last Updates (max 5)

(2009-12-19) Moved several long-term user-carts into the Apps menu Added 'redraw' and 'clear' to the debug window Updated Breakpoint system with ability to specify memory ranges Changed breakpoint tag for timing code (now needs just one entry) Increased minimum sound jitter buffer to reduce garble Fix output when audio voice set to 0 (not flat) disable audio debug to disk (was not meant to be on!) (code) re-laid-out cartridge structs and created new breakpoint struct When config file not present, set up defaults for disks run audio and speech thread at higher priority change default 379 bank to last one made 'step over' not show the stepped over instructions in the debugger when system running very slow, don't update speech (temporary workaround) changed "slow cpu" to run as slow as possible (about 60hz right now) Made 99/4 not have a bitmap mode don't lose the current directory when saving a snapshot (code) changed nasm command line

(2009-11-26) Disable the audio.raw debug log which was causing many issues! Note: source not updated

(2009-11-12) Too many to list - over sixty updates! New sound core is a big one Fixed the Tunnels of Doom load Debugger updates, new shortcut keys, heatmap See the forum post or 'whatsnew.txt' for full details

(2009-08-09) More filesystem debug Added ability to set Program Counter (disasm page) Added better description of file header mismatch Added better detection of TIFILES header Fixed broken host text file fixed/variable determination Commented out speech and dac warning debugs (they don't help) Print one less debug line to window to avoid last line being masked

(2009-08-04) Bugfix to last build which broke V9T9 file headers

Notes
Note: this is a beta release. I'm not done all the improvements yet. Use with care
