Today just gets better and better as after already showing off an early concept port of AGONY on the MSXTurboR, now we have the first proper glimpse of Super Mario running on the TI-99/4A with F18a Video Upgrade as a project by Asmusr. In development since early 2016, this Super Mario remake from the NES, is being programmed in TMS9900 assembly language without the use of the original source code, has graphics imported from the spriters resource and reworked in Magellan. and music is entered by hand into Mod2PSG2.
Furthermore the code is being assembled using ralphb's cross development tools, testing and debugging using his own js99er.net emulator, and the coder aims to have at least one fully playable level, with sub-levels and all of the original details included.
