Front-end for M4 board in ROM

[Swainy]

Ok, it’s not the SD card after all. Although it is sort of SD card related. My M4 board doesn’t read the card when I first switch it on unless I hit the M4 reset button. Is that normal? I haven’t used it in a while but I did update the firmware yesterday.

Hi everyone, I got my M4 back from Duke as I had to send it back for repair as the SD card was not always working. Anyway, it's back and it's now working fine, I've installed the front end and again that too is mainly working great, especially when using compact images from http://cngsoft.no-ip.org/


However, I'm trying to load the 128k version of Double Dragon, it loads the trainer fine and then tries to load from Disc A.



I'm still not sure that the M4 rom that I've got is the correct file. Where exactly are you guys getting that file from?


Thanks in advance.

There are games that access directly to disc hardware instead of using the firmware calls, so the M4 hooks don't work with them. What I do in those cases is to write the games to disc using the included M4FE feature, and then play them from disc.

Thanks guys but where do I find the M4 rom?

Ignore my edited post...


The M4 rom is automounted at slot 6

Ok, only mine doesn’t say that it’s mounted? I guess that’s normal?

[VincentGR]

Yes, I think I named it back then.

Are you using the modified lowerrom? -Otherwise this is a message you will often see when the discrom is re-initialized.
You can try this installer to setup the modified lowerrom:

No where. The M4 rom file is embedded into the M4 board.
The slot which the M4 is set to (ie. 6) is occuppied by M4. However you can still upload a rom to that slot. It will not show, unless you do |M4ROMOFF

Ok, I've now put that version of the lower rom into slot 31 and Double Dragon (the Cache version) is still trying to load from disc. Where should I be downloading the Amsdos rom from?
