MESS and TI cartridges

Working with MiniMemory

MESS versions 0.126 to 0.131

When you want to use the Mini Memory NVRAM, you have to mount a pseudo module besides the Mini Memory GROM and ROM. This pseudo module must have a name ending in *m.bin, like memorym.bin. When you save a program using SAVE MINIMEM, a file is created in the nvram/ti99_4x subdiretory which corresponds to this pseudo file. That is, you can choose different NVRAM buffer files by selecting another pseudo RAM file. Note that the pseudo file itself is loaded but not transferred to memory.

MESS versions 0.132 and later

When the MiniMemory RPK is plugged in, the emulator automatically creates the NVRAM file. The name of the NVRAM file is determined in the layout.xml file in the RPK, so you can create different instances of the MiniMemory cartridge by choosing different NVRAM names.

To instantly clear the NVRAM, just delete the NVRAM file.
