A native PC port of NBA JAM: On Fire Edition (Xbox 360, XBLA, 2011), built with ReXGlue. Not an emulator: the original PowerPC code is statically recompiled to C++ ahead of time and compiled for x86-64.
It runs and it plays.
You need your own copy of the game. NBA JAM: On Fire Edition was sold on Xbox Live Arcade, and a purchased copy sits on the console's drive as a single signed container file. Nothing here ships game content and nothing here will get you a copy.
Download the release, unzip it next to that container file, and run NBA JAM Mod Manager.exe. It unpacks the game, sets the folder up, and from then on it is the one window you need: install a mod, choose which one loads, play. See RELEASE.md for what is in the download and what it does.
The PS3 modding scene for this game is alive and its mods run here. They are published as PlayStation 3 packages; the manager opens one, converts its artwork into the format this build reads, and gives it a game folder and a save file of its own. Installed mods are listed on the game's own main menu, in the panel where JAMnet used to be:
Hold the left trigger and press Y there and the panel wakes up: the orange box becomes a cursor, A loads what it is on, and the game comes back up in that mod about fifteen seconds later.

The port project only — the configuration, hand-written source, and the tooling built along the way. It contains no game content. You need your own copy of the title; the build reads an extracted XBLA package and never redistributes it.

Boots to gameplay, and runs as the full version rather than a trial. Roughly 53,000 recompiled functions register with none rejected; all 320 kernel imports resolve; graphics, audio, input and the achievement store all initialize. The EA Sports intro video decodes correctly.
PS3 mods run on it. All three published ones install from their original packages and play.
Known rough edges: the Xenos backend logs a stream of "invalid" texture fetch
constant warnings during play, and memmap:\clips\ is unmapped.
The eventual target is an original Xbox port, which inverts most of the constraints — 64 MB unified memory against the 360's 512 MB, one 733 MHz Pentium III against three 3.2 GHz PowerPC cores, fixed-function-era shaders against the Xenos. This PC build exists to establish a correct reference to diff against.
