Open82 is a project by Andrew Owen and Matthew Westcott to produce an open source version of the ZX Spectrum ROM. As of 1 January, 2008, it's currently very much in the alpha stages, but does manage to load some commercial games successfully. This page is a place to list which games it works with, which it doesn't and why, starting with the Top 100 from WoS.

- ↑ The crash appears to be due to the method used to embed the Speedlock 7 loader in BASIC; if you use an emulator with the standard Spectrum ROM to freeze the loader on execution and dump it (0x5D06 - 0x6AF5), then load the dumped memory block into an emulator with OpenZXRom and begin execution from 0x5D06, the loader will then decrypt and run without problems. The game itself works up until the end of the first level, at which point it stops at 0x0562 when trying to load the second level from tape.
- ↑ The crash appears to be due to the method used to embed the Speedlock 4 loader in BASIC; if you use an emulator with the standard Spectrum ROM to freeze the loader on execution and dump it, then load the dumped memory block into an emulator with OpenZXRom and begin execution from 0x5D06, the loader will then decrypt and run without problems. The game itself appears to work perfectly; I successfully tested it up to the beginning of the second level.
- ↑ Screen is actually 0x1C00 bytes loaded using LOAD"" CODE 16384, and all hell breaks loose when loading finishes.
- ↑ At least under Fuse there are problems with recognising the BASIC header.
- ↑ At least under Fuse there are problems with recognising the BASIC header.
- ↑ I was able to get the loader to run in a similar fashion to some of the Speedlock games I've tried but the process was a little more involved; I had to create a makeshift manual snapshot by freezing and dumping the loader and noting the current state of the registers using the standard ROM. Loading the dump back into memory and recreating the state of the registers allowed the loader to run in OpenZXRom. The game itself crashes when you pick up a weapons burger, ending up in an infinite loop at 0x0DE7.
- ↑ If you use an emulator (with the standard Spectrum ROM) to freeze the loader on execution (0x5D11 on a regular 48K Spectrum), dump the loader (0x5D11 - 0x5E1A) then use bin2rem on the dumped loader it actually works, so the problem appears to be with the method of storing the m/c loader in the BASIC program rather than with the loader itself. After the game has loaded, it stops at 0x03B5.
- ↑ On adding this stub in the right location, the loader resets a couple of seconds before the end.
