It retailed for $525 USD, which is equivalent to $1,490 after adjusting for inflation (in 2020)! Partially due to its exuberant price and lack of software support, it only sold around twenty-thousand units. The TI-99/4A is an incremental upgrade to the original TI-99/4, at half the price of the original unit. Needless to say it was much more successful, selling around three **million** units. Support for this system was introduced with Batocera **v33**. Does Batocera support emulating both models? Good question!

The BIOS file can be placed in any one of the following locations: * ''roms/ti99/ti99_4a.zip'' * ''roms/ti99/ti99_4a.7z'' * ''bios/ti99_4a.zip'' * ''bios/ti99_4a.7z'' ===== ROMs ===== Place your TI-99 ROMs in ''/userdata/roms/ti99''. Cartridges need to be in ''*.rpk'' format and unzipped. The MAME software list files (''*.bin'') will not run properly. ===== Emulators ===== ==== MAME ==== [[https://www.mamedev.org/|MAME]], the Multiple Arcade Machine Emulator, is a multi-purpose emulation framework which facilitates the emulation of vintage hardware and software. Originally targeting vintage arcade machines, MAME has since absorbed the sister-project [[http://mess.redump.net/start|MESS]] (Multi Emulator Super System) to support a wide variety of vintage computers, video game consoles and calculators as well. MAME doesn't use an individual "core" for each system like RetroArch does, instead the ROM itself usually contains the necessary information to accurately emulate it, thus making it specific to the version of MAME it was made for. Overall it's a very complicated subject, we have a [[:arcade|guide specific to arcade]] just for it. === MAME configuration === MAME offers a **[[https://docs.mamedev.org/usingmame/ui.html|Menu]]** in-game (''[HOTKEY]'' + {{:wiki:south.png?nolink&20|South button (B SNES)}} or ''[Tab]'' on the keyboard). This can be used to manually adjust inputs or game settings. If you're having issues with a specific game, check the [[https://wiki.mamedev.org/index.php/FAQ:Games|MAMEdev FAQ for that game here.]] For MESS systems specifically, you might find more information on [[http://mess.redump.net/start|MESS's wiki]]. All options can also be edited by opening the ''mame.ini'' file.
