devres_icon_star_gold_hof2.png

Power BASIC TI-99/4A
This is a port of the 'Power BASIC' interpreter used with the TMS9995-based Powertran Cortex machine.
It is written in pure assembly. Graphic commands, sprites and saving to disk are supported. Currently no sound and speech supported.
Power BASIC instruction manual available.

Playground TI-99/4A
Playground is a package that makes it possible to create assembly language programs that can be run from TI BASIC on an unexpanded console
using only a cassette player to load the program (!)
Although primarily intended for BASIC, programs written for playground can be run from XB, saved in E/A 5 format, loaded into a supercart,
and even made into an actual cartridge.
The manual describes in detail the differences in style necessary when programming for an environment that runs in only 256 bytes of memory.
There is a library of subroutines for printing text, printing a number, shifting blocks in VDP, generating random numbers, using the line editor
from BASIC, HCHAR, VCHAR,GPLLNK, a bit reversal routine, and a fast scroll routine.
Source code is included for three different programs that should help you get started.

XB256 - Expanded Graphics for TI Extended Basic TI-99/4A
XB256 is a collection of assembly language subroutines that give the Extended BASIC programmer much more access
to the graphics capabilities built into the TMS 9918A video processor. No knowledge of assembly language
is required to use XB256 - programs are written completely in Extended BASIC.
The average TI user can now take advantage of graphics capabilities that were built into the computer,
but never before available without having to program in assembly language.
XB256 lets you select from two independent screens. Screen1 is the screen normally used by Extended BASIC and
is accessed exactly as described in the XB manual. Screen2 lets you define 256 characters, compared to the 112
normally available to XB. Additionally, you can use up to 28 double sized sprites using the patterns available to Screen1.
You can toggle between the two screens as desired and preserve the graphics on each screen.
When using Screen2 there are assembly equivalents that replace CHAR, CHARPAT, COLOR, and CHARSET.
Except for these subroutines, screen access in Screen2 is by the usual Extended BASIC statements
such as PRINT, SPRITE, ACCEPT, etc.
There are scrolling routines that allow you to scroll screen characters left, right, up, or down.
Other routines let you scroll smoothly one pixel at a time to the left, right or vertically.
You can specify a window area for scrolling and leave the rest of the screen unchanged.
There are some miscellaneous subroutines that let you hilight text, set the sprite early clock, print on the screen using
all 32 columns, read from or write to the VDP RAM, write compressed strings to VDP, and move sound tables into VDP.
A utility is included that lets you save selected areas of VDP memory into compressed strings that can be merged
with your program. You can save character definitions, sound tables, screen images, etc. in a more compact form that
can be loaded much more rapidly.
There is a sound list compiler that lets you write music and sound effects in XB, then save them in a compressed form
that can be loaded directly into VDP memory. This is more compact, plus your program is free to do other tasks while
a sound list plays. Also, two soundlists can play simultaneously.

The Missing Link 2.0 (TML) TI-99/4A
The zip archive contains "The Missing Link 2.0" and its documentation. This was published by Texaments in 1990.
It gives the XB programmer easy access to the bit mapped features of the 9918 VDP.
Full color cartesian graphics, turtle graphics, sprite graphics (32 sprites with auto motion) are supported.
Text can be displayed on screen with fonts having sizes ranging from 4x6 pixels to 8x8 pixels.
The manual is updated with many previously undocumented features. A tutorial called "Potatohead" is included.
There is a loader that embeds A/L programs in high memory - they can be saved as an XB program and run directly out of high memory.

GNU C Compiler (GCC) win + linux + osx
GCC for the TMS9900 allows you to cross-compile C programs on your PC (Linux, OSX or Windows) for the TI.
Insomnia's release contains a set of patches against GCC 4.4. Just check out the code from the GCC project, apply the patches and build according to the build instructions
for your platform and you're on your way to write programs and games for the TI in a high level language that rival the speed of assembly. And if you need just that little
bit extra in terms of speed, you can always inline TMS9900 assembly for the critical sections of your code and compile everything with the same toolchain.
For access to the VDP, the SN76489, etc... you can use Tursi's ti99 library, which you can find in the GCC thread.
Hop over to the INSOMNIA LABS blog for background information on this port.
Check the "Setting up the GCC compiler for the TI-99/4A" video by Tursi for detailed steps on how to build and install GCC on your Windows PC.

  • classic99
    Windows-based emulator including TI-99 ROMs under license from Texas Instruments
    Best debugger, OS file support, support for 64K bank-switch carts
    Status: Still under active development
  • MESS
    Multiple system emulator that supports the TI-99/4A
    Basic debugger, most accurate emulation, support for 64K bank-switch carts
    Status: Still under active development

The MESS debugger has many features that the Classic99 does not have and vice versus.

Classic99 supports 128k bank switch carts, actually.

For MakeCart, today it only outputs GROM code - you can't burn the result to an EPROM and have it work (so the comment is a little misleading). I did start the ROM output version though and will get that done eventually. ;)

Noted, I've just adjusted the wording a bit. I also just checked the debugger page at MESS wiki;
The debugger really has some features I didn't think were there. Cool :cool:
I'll also try to be more objective ;)

Oh, on a sidenote, I just checked David Pitts' page and his asm990 cross-assembler runs on Linux, now supports
macros and has a "TI-99/4A mode". It can't create any cartridge images yet. But definitly worth testing more.
I'll be adding that to the resources together with TI-asm.

Although MESS does not have a "memory heatmap" as Classic99, you gotta love the flexibility of MESSí watchpoints ...

Examples:

hotspot 0,10
Looks for hotspots on CPU 0 using a search buffer of 16 entries, reporting any entries which end up with 250 or more hits.

hotspot 1,40,#1000
Looks for hotspots on CPU 1 using a search buffer of 64 entries, reporting any entries which end up with 1000 or more hits.

wp 1234,6,rw
Set a watchpoint that will halt execution whenever a read or write occurs in the address range 1234-1239 inclusive.

wp 23456,a,w,wpdata == 1
Set a watchpoint that will halt execution whenever a write occurs in the address range 23456-2345f AND the data written is equal to 1.

wp 3456,20,r,1,{printf "Read @ %08X\n",wpaddr; g}
Set a watchpoint that will halt execution whenever a read occurs in the address range 3456-3475. When this happens, print Read @ <wpaddr> and continue executing.

temp0 = 0; wp 45678,1,writeval==f0,{temp0++; g}
Set a watchpoint that will halt execution whenever a write occurs to the address 45678 AND the value being written is equal to f0. When that happens, increment the variable temp0 and resume execution.

:cool:

... possibility to record AVI movie ...

With or without sound, I donít think that is important features. There are many excellent screen and window video grapping software applications available and also for free.

I sometimes use Camtasia Studio to grap, zoom and analyze pixels and animations frame by frame.

Also, feel free to delete my comments/viewpoints, as to keep this thread a bit "clean".

... support for 128K bank-switch carts ...

Now that Classic99 supports 128K bank-switch carts, you might add MESSí ability to support RAM in cartridges with "type of" Mini Memory (4K persistent), MBX (1K persistent) and SuperSpace II (32K).

Yes, you should be able to make games using persistent RAM to keep track of high scores, remember settings, save and load game facilities etc. - all ultraquick !

The feature lists will start getting very long if we put in all the little features. Classic99 supports RAM in cartridges too (just not persistent, nobody's ever asked for it ;) ). I think it's fine that there's a summary list and a link, so long as what's listed is accurate and relatively independent.

I just downloaded the latest version of MESS, and contrary to the last one I used, the TI-99 emulation doesn't support cartridges anymore! Can anyone tell me why this has been removed and how cartridges can be loaded into MESS now?

Well, MESS does still handle cartridges. There is a new format for storing ROMS.
The ROMS are now in .rpk files (basically a zip file with .rpk extension containing rom and metadata).

Check here:
http://ninerpedia.or...MESS_ROM_format

and here:
ftp://whtech.com/emulators/cartridge_images/rpk/

Yep, as of version 0.135. Unfortunately the old method has been cancelled and even makes the system crash. The new method takes more and newer types of cartridges.
