Just dumped the BIOS of my Frael Bruc 100 with SAVEROM but I need to send files to mars2000you, and so, can you reply to my e-mail for confirmation? Thankyou in advance.
Enribar has a different version. openMSX emulates version 2 of the machine with firmware 1.2 (no menu) or 1.3 (menu scuola 3F), but Enribar's machine has menu scuola 2F (i guess it must be firmware 1.1).
As for other versions, an EPROM reader is required to dump the firmware rom.
it means too that firmware 1.0 is only used for version 1 of this computer.
I have a Sakhr AX-150 and I attempted to dump the ROMs from it. I got some dump files (one for main/BASIC ROM, one for Arabic ROM) but I don't know how to test them. Is someone here interested in taking a look at them and possibly getting this model emulated?
Added many photos of internals and screenshots of execution results for all the tools. Only missing part is keyboard matrix which requires pressing combinations of keys and taking pictures at the same time which is not possible by myself :)
From your rom dumps and the existing YIS-805/128R2 machine config I created a machine config and systemroms. I bundled them here.
I dumped two different ways, both using a MegaFlashROM SCC+ SD cartridge as the storage device. For both I booted in English mode by holding CTRL, since it seems to be the only mode where MegaFlashROM SCC+ SD can detect the memory cards on this MSX.
The first pair of dumps was taken using SAVEROM.COM from NEXTOR. The second pair of dumps was taken using GETROM.BIN from the MSX-DOS 1 included with NEXTOR by booting while additionally holding "1". In both cases the data read out was identical.
In each case:
MSX.ROM was dumped from slot 0-0 addresses 0000-7FFF
ARABIC.ROM was dumped from slot 0-1 addresses 4000-BFFF
Here's what the "file" command says about them on my Mac:
If a dump is needed from Arabic mode instead, please let me know how I might be able to do this. I also have a Mapper MegaRAM 512KB in case that is helpful. I am currently lacking the necessary cable to connect this computer to my arduitape. The general purpose ports on this computer appear to be defective, unfortunately — joymega does not work with a Sega controller. I also don't have any cable for the printer port.
Small update: I was able to dump from Arabic mode too, by putting Mapper MegaRAM 512KB in slot A in Mapper mode, putting MegaFlashROM SCC+ SD in slot B, and booting in MSX-DOS 1 mode with Mapper MegaRAM storage driver disabled (CTRL+1+DEL during boot), I was able to dump using GETROM.BIN from Arabic mode BASIC LAUNCHED using "BASIC" from MSX-DOS, then "5" to exit the Arabic menu to BASIC prompt, and finally BLOAD "GETROM.BIN",R
The images dumped this way are identical to the ones dumped from ASCII mode
