Quote from: rpalmer on 23:06, 27 February 21There various different lower ROMs to handle the different keyboard layouts.1. The default UK English/Australian QWERTY layout.2. The French with the AZERTY layout.3. The German layout with accented keys.4. The Spanish layout with different accented keys to the German layout.I think that is most if not all.As for BASIC ROMs there are several notably 1.0 and 1.1. There are several other with patches for fixes to routines and speed up of others.The sign on message is based on the link setting on the motherboard which are used as an index into a table of possible sign on messages types.
Quote from: Animalgril987 on 21:57, 04 March 21Can your diagnostic ROM be used in an M4 or Romboard?Great video, nice detective work.
Quote from: vasilisk on 22:23, 04 March 21Is it possible to have a dsk version of this diagnostic rom?

Quote from: llopis on 18:11, 06 March 21OK, that's good that it exists. I would need a way to do it from assembly and to turn it back on after I'm doing checking the system lower ROM. I'm looking through the M4 dev info but I don't see it. http://www.spinpoint.org/cpc/m4info.txt Any ideas?
Quote from: Animalgril987 on 19:27, 06 March 21I don't have a disassembler capable of looking at ROMs at the moment, or I'd look at the M4 command jumpblock to find the entry point for the RSX. And it has probably moved depending on version number. Hopefully @Duke will see the post and will be able to help. Alan.
Quote from: Duke on 09:39, 07 March 21I've just added a feature to latest M4 Firmware v2.0.7, so you can change lowerrom on the fly from the one uploaded to the romboard to the system or even the HACK menu one.It's this command:C_ROMLOW 0x433D Implemented v2.0.7. Map lower rom : data = 0 system lower rom, 1 = lowerrom from romboard if enabled, 2 = lowerrom from HACK menu.You can see various examples here on how to send commands to the M4 board:https://github.com/M4Duke/M4examplesA version check is probably a good idea, since this is a new feature.
Quote from: SkulleateR on 20:05, 20 March 21I'm sure I downloaded THAT one, but k, now it works Guess the UNKNOWN Rom (Lower) is the modified 6128 rom then ....Ok, still don't know why I cannot start an 128KB game but I guess I will put this into another thread since it's not connected to ADR then ... thx
