NFSHP2 v1.0.1

An unofficial homebrew port of the PS2 version of Need for Speed: Hot Pursuit 2 to the New Nintendo 3DS: the PS2 game's code, reverse-engineered from the retail disc and reimplemented in C. It plays from your own disc's files. No game data comes with it.

What's new in 1.0.1

A fix release. On a disc whose file list differs from SLES-50731's, 1.0.0's tools/zdir_extract.py put files under each other's names. The sound banks then failed to convert, and the 3DS crashed at boot.

• tools/zdir_extract.py now names each file by its hash, the way the game finds it. It lists any names your disc doesn't have, and it refuses a folder that the old version made.
• tools/audio_pack.py and tools/make_card.py stop with a message saying what to redo, instead of a Python error. make_card.py --prune also deletes old files from the card (it keeps NFSHP2/SAVES).
• If a data file is missing or wrong, the port now stops at boot with a message naming it instead of crashing.

If you set up the SD card with 1.0.0's tools, download this version's source, delete extracted-retail/, and do README steps 2 to 4 again. Run step 4 as python tools/make_card.py E:\ --prune (with your SD card's drive letter). Your saves are kept.

What you need

• A New 3DS, New 3DS XL or New 2DS XL with custom firmware (Luma3DS) and FBI. An Old 3DS or 2DS shows a message at boot and stops.
• Your own PS2 disc of Need for Speed: Hot Pursuit 2. It was made and tested with SLES-50731, the PAL version. Other discs should now extract correctly, but the game hasn't been tested with their files.
• About 2.9 GB free on the SD card, and a computer with Python 3.8 or newer.

The README explains how to put the disc's files on the SD card.

1.0.1 has been tested in the Azahar emulator. 1.0.0 was also tested on a real 3DS, and 1.0.1 only adds the data checks above.

Known issues

• On Ancient Ruins, at the curb turn by the cones, the road can vanish for a frame or two.
• The frame rate drops below 30 in the heaviest places: the fire on Coastal Parklands, the end of Desert Heat, and by some roadblocks.
• On Coastal Parklands, the low stone wall before the tunnel can look blocky and flicker when seen side-on.
• Attract mode doesn't play the disc's demo replays: on the 3DS they leave the PS2's path after one frame, so it plays its AI race demo instead. DemoReplays 1 in the config file turns them back on.
• In Local Wireless, the consoles can fall out of step just after a player finishes (two races in eight in testing): that car, driven by the CPU from the finish on, can end up in a different place on each console.
• In French, the LOADING screen and the Need for Speed logo keep their English art.
• The language screen at boot appears at once, without the PS2's slide-in.
