NBA Jam Midway, 1993 (rev 3.01 4/07/93) NBA Jam Tournament Edition Midway, 1994 (rev 4.0 3/23/94)

Pick the game from the list when you start the core.

Midway’s T-unit board in gateware: the TMS34010 graphics CPU, the DMA blitter, two 16-bit frame buffers, and the Williams ADPCM sound board (6809, YM2151, OKI6295, DAC).

ROMs are not included. Build the images from your own MAME romsets with mra_build.py and nbajam.mra / nbajamte.mra, and copy them to Assets/nbajam/common/ (nbajam.rom, nbajamte.rom).

Laid out like the arcade panel:

• Y turbo (R also)
• X shoot / block
• A pass / steal (B also)
• Select coin, Start start

Two credits start a game. A new board shows CMOS INVALID: press any button.
