Un très bon émulateur de TI-99/4A tournant sous Windows. Il fut connu sous le nom d’AMI99, mais renommer, beaucoup de personne pensait qu’il s’agissait d’un émulateur Commodore Amiga.

-Got 9901 timer code working correctly (I believe) thanks to Sudoku from http://sometimes.99er.net
– Now OLD CS1 times out like it should (hey, it was newsworthy for PC99 😉 ) In all cases the 9901 timer countdown is tied to the CPU speed.
-Set CPU speed back to 3.0MHz – that’s what everyone seems to say. I really need to test it now that I know how the 9901 works. If you want 3.3 you can overclock in the options menu anyway.
-Fixed loading of larger cartridge files which were sometimes truncated.
-Added range checking to ROM loader to prevent corrupting memory
-New configurations for CPU Throttle – 3 modes: Normal, CPU Overdrive, System Maximum
Normal: Runs the system with normal throttle, CPU/System speed can be tuned in the options menu, but defaults to 3MHz. Very little impact on the host CPU in most cases.
– CPU Overdrive: Detaches the CPU from the system and runs it as fast as possible, sleeping occasionally to reduce load on the host CPU. VDP still fires at 60fps – this means that interrupt driven functions such as sprites will still run at the correct speed. This mode is potentially useful for speeding up Extended BASIC games while still leaving them playable.
– System Maximum: All parts run as fast as possible. This is new to Classic99 but is the traditional means of unthrottling in most emulators. This will spin the host CPU to 100%.
