The key positions of the TI-99/4A rather than of the emulating keyboard. For example, my minus/underscore key produces equals/plus character, the left bracket key produces the forward slash character, my quote key is Enter, etc. Ideally, an emulator would automatically map the keys correctly, so (for example) my Backspace key would work.

There are essentially two Mac emulators for the TI-99/4A: MacV9T9 and MacMESS. The former is Classic-only, making it unusable on modern Macs (since Classic does not run on Intel-based Macs, or any Mac running Leopard). This essentially leaves only MacMESS. One drawback to MacMESS is that it lacks the ROMs, making it difficult for any newcomer simply wishing to try it out. However, this can be overcome with sufficient initiative. Another drawback is its usability.

I notice that my mouse simply disappears, preventing from me easily swapping between applications. Furthermore, the keyboard mapping is incorrect for emulation, assuming the key positions of the TI-99/4A rather than of the emulating keyboard. For example, my minus/underscore key produces equals/plus character, the left bracket key produces the forward slash character, my quote key is Enter, etc. Ideally, an emulator would automatically map the keys correctly, so (for example) my Backspace key would work, not forcing me into Option-S, etc. Part of this I understand has to do with the fact that MacMESS is a general emulator, being all things to all people. By emulating the dozens of systems it does, its design decisions are much more general and will not be tailored specifically to the TI-99/4A. I noticed that none of these defects are seen in the Classic 99 emulator on Windows.

It even includes the TI Roms, licensed from Texas Instruments. Does anyone know if there are any plans to port this great program to the Mac? Regards, Jonathan MarkWills, 14:12 น. The source is distributed with the executable, so any Mac guru could take a look. I'm not sure if its rather tightly bound to the Windows OS though.

The author, Tursi, is a very friendly chap and would probably offer advice to any potential porter. One word of warning: Tursi has permission from TI to distribute the roms and groms with Classic99, however I doubt very much if that permission would extend to ports of his software.

I would imagine the author would have to apply to TI in his own right. Regards Mark MarkWills, 8:32 น. I mentioned it to Tursi, and got this reply: > It is very tightly tied to Windows - DirectX and GDI (depending on the mode you > use), however since it supports both I'd imagine one or the other is portable to > SDL without too much trouble.

FlashROM 99 by endlos99 FlashROM 99 A Flash ROM Cartridge for the TI 99/4A FlashROM 99 The TI 99/4A Flash ROM Cartridge, or FlashROM 99 for short, is a cartridge for the TI 99/4A home computer that allows for running ROM cartridge images stored on an SD card. The FlashROM 99 supports ROM-only images of up to 32K that use the write-to- >60xx bank switching scheme. It will not work with programs using GROMs or CRU-based bank switching. The cartridge does not require the Peripheral Expansion Box and runs on both PAL and NTSC consoles. FlashROM 99 is released as Open Source Hardware under the and the.

Both hardware design files and firmware sources are available on. The project homepage is hosted at. How to Start with the FlashROM 99 Using the FlashROM 99 is simple and doesn't require and special hardware or software. To begin, copy up to 171 cartridge image files onto an SD or SDHC card. Switch off the TI 99 and plug in the FlashROM 99, then insert the SD card into the FlashROM 99.

Switch on the TI 99 and wait until the activity indicator on the FlashROM 99 is no longer lit. Press any key to bring up the TI menu screen. You should see the list of images found on the SD card. If the SD card contains more than 8 images, a FLASHROM 99 entry is shown instead. Selecting this entry starts an image browser where you can page through the list of available images with,,., SPACE, and number keys.
