.rom's from 128K doesn't load #5

Closed old-delab closed 2 years ago

old-delab commented 3 years ago

I tried to replicate your wonderful project on a Lolin 32 Lite board, but the .rom's from 128K doesn't load (everything goes back to 48K mode). In 48K mode, everything is fine. What can be done?

Does Lolin 32 Lite board have PSRAM?

DrNorfolk commented 2 years ago

I will describe this problem here for someone in the future. Lolin 32 is based on a wroom-32 chip that has no PSRAM memory. To work with 128kb of firmware, you need a chip WROVER that has PSRAM memory

In continuation of this question. I can't run ROMs PLUS3 and PLUS3E. The terminal says that everything was loaded successfully, but I only see a black screen.

At first I thought the problem was that PLUS3 and PLUS3E are four parts (0.rom, 1.rom, 2.rom, 3.rom ), while SINCLAIR and PLUS2A are two parts (only 0.rom, 1 .rom). But I tried adding PENTAGON128 ROM and it works. It consists of files 128p-0.rom, 128p-1.rom and trdos.rom. I renamed them to 0.rom, 1.rom, 2.rom. In general, this works, except for the trdos.rom part. It would be very interesting to see this in action. Has anyone encountered such a problem? Thank you!

I have removed PLUS3 and PLUS3E. I inherited them from original fork and they never worked. Probably, a disk controller emulation is needed, and I do not have plans on implementing it.

  I recommend a program for a TV set-top box on Android — ZX Spectrum Emulator. Everything works perfectly and is compatible and cheap, and with the Internet!
