Getting ROMs for MESS
From Ninerpedia
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:
The emulator does not ship with any ROMs. There are ROMs available on some servers; use your favorite search engine. But note that most ROMs are distributed on the assumption that you have the original ROMs in hardware that you purchased. Downloading the ROMs of hardware that you do not have may be a copyright violation. In doubt, contact the copyright holders.
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).
