While the simulation of hardware circuits is in no way problematic with respect to copyright (since we produce a new system by observing the behavior of the original one), the distribution of memory contents is generally subject to copyright, and unlicenced distribution is considered an offense by most jurisdictions.
Some countries know exemptions in the case of legacy software that is not runnable without the hardware, when the hardware is not available anymore. Other countries do not have corresponding exemptions. So you have to be aware of the following:
Consequently, I will not provide links for downloading these files. Find out by yourself how to get them. The safest way (from a legal standpoint) is to dump the contents from the real equipment if you own such a system.
At least for the TI-99/8 we have a written consent from TI that the ROM contents may be freely distributed. For TI-99/8 ROMs have a look at Planet99.net (login required).
Rumours are that you should also try the FTP site of WHTech.
The ROM dumps used for the TI emulations can be identified by this list. The required files must be present when starting the emulation. If an optional file is missing, the emulation will run, provided that the affected component that needs the ROM is not accessed. You will get a warning message stating that ROMs are missing and that the emulation will probably not run correctly.
Systems may be parents of others. In that case, the child systems borrow the ROM files from the parents if they do not have them in their own ZIP file. This means that if you have the ti99_4a.zip file, you can always launch the European version ti99_4ae since all files are equal, and the ti99_4a is the parent of ti99_4ae.
- ti99_4 is the parent of ti99_4e (european version)
- ti99_4a is the parent of ti99_4ae and ti99_4ev
- ti99_8 is the parent of ti99_8e
MAME is tolerant about the file names inside the ZIP files; the only important key is the hash code. ROM contents are compared by their hash code to make sure that the contents are authentic. Files may be renamed within the ZIP files.
The following table refers to MAME versions 0.212 and higher. The ROM dumps are distributed over a set of ZIP files. Each ZIP file corresponds to a single system or peripheral extension.
Main systems
These are the ROMs for the consoles, the Geneve, and the SGCPU.
