That is quite unusual, what model of router do you have?
M-Net router, but that's not the point. Slowly the overloading of radio waves will strike everywhere. Therefore a M4 card with cable plug would be great - just an idea.  :)

Or maybe @Duke can do something with Imperium, and being able to connect an USB to RJ45 adapter to CPC...  ::)

Well today I finally added the 'hack' button to both of my early revision 2.4 M4 boards.


It might not look the prettiest *See the attached pictures), but it works perfectly, thanks @Duke these boards are just brilliant.

Hi Duke,


In my Who wants to make a MMOG in the games group...


Would it be feasible to have a special M4 function that could work for any similar type of task that is... polling a URL, taking a payload of a defined size and having it either overwrite the same RAM as fast as possible, or a sliding portion of RAM (offset for each fetch until a certain number of fetches before overwriting again)... Or would it be just as fast if coded in Z80?  This would allow online games to have their payload received as fast as possible to the CPC, hopefully without the CPC being too busy with the comms.

I don't think so. It should be plenty fast as it is. Anyway it would be easy to test how fast it is.
Ie. use the httpget example from  https://github.com/M4Duke/M4examples/blob/master/httpget.s, setup a php script to measure how frequent it is pulled and loop the code on the CPC that pulls the corresponding url (and of course only DNS lookup once).

Hi Duke,
I try to connect my M4 board to my internal network. Changed from static IP to DHCP. If I do this |NETSTAT says "No AP found". What does it mean?

I get this message if the WiFi signal is too weak. But it may has other reasons like something is not correctly configured.

Thanks Gunhed for the issue with the configuration.
I changed the config.txt file out of lazyness with protext (programmer mode) but after saving the file it added a lot of stuff in the beginning of the file. I assume the header. So the config.txt file wasn't read properly. my fault.  :picard:

Yes, this can happen when using Protext document mode. It adds a 128 byte file header.
What works is Maxam Editor or the Protext prgram mode (no header).

Read this thread, should get you started with games/dsk's real quick:

And some additional guides here:

well, after a short period of banging my head on the wall, i got my first game loaded (dizzy, naturally), i even saved a snapshot image so i can return to it later...

the main things that i struggled with were finding the ¦ key (never needed it before and all the instructions i read made it look like a solid line, felt like an idiot once i'd worked it out, scoured the entire cpc manual and found no reference to it!), and the fact that i'm using a cpc464...
everything was fine once i'd put ROMUP464.bin on my sd card and run it... that should be the first instruction in any tutorial written for the M4...  :)

i've only faffed for an hour or so, but i am extremely pleased with my purchase...

additional...
i had the full day available to play yesterday (sunday), no other plans apart from eating and entertaining my cats, so, 9am i booted up the CPC...
my initial plan was to finally check out Pinball Dreams but it didn't take long to realise that i couldn't load it cos the 464 only has 64k of ram and the game needs 128k... so, change of plans, i then decided to check out as many other homebrew games as i could, in alphabetic order...
i'd grabbed the M4backup.zip, so i went to the "novita" folder and started at the beginning...
i'm not a fan of the 2048 games, so i skipped that...
next up was 3D Racing One, didn't fancy a driving game at the time, so i skipped that too...
third game in the folder was A Prelude To Chaos, never heard of that one, so i loaded it up...

*time passes*

at 10.20pm i finished the game...

yesterday was a very good day...  8)

Hello,
is there a way to use the M4 with a game needing the |CPM command ?

I wanted to launch the Tristam Island demo.
Maybe a CPM ROM modified for M4 ?

I tried http://www.cpcwiki.eu/index.php/CPM_Plus_ROM but it doesn't work, when I type |EMS it says "Second CP/M PLUS ROM not present", I tried loading CPM1.ROM in slot 3, CPM2.ROM in slot 4 or the accessory ROM from http://www.cpcwiki.eu/index.php/CPM_Accessory_ROM_1 in slot 4 but same error message.

From @TotO XMem or MiniBooster Start Disc there are two CP/M Roms which should be installed (e.g. slot 8 and 9). http://centpourcent.net/
I'm using those ROMs for launching CP/M and the Infocom adventures.
Should work.

Thanks for the information. Both are installed in slot 8 and 9, no boot message though and |CPM still use the real floppy drive.
I have M4FE at slot 2, and FW v3.12 as slot 31

@genesis8 is asking about games/demos that launch *using* |CPM, not games that run *under* CPM.  :picard2:


|CPM just loads a bootsector to &100 and jumps to it, so while there's no reason that part can't work on the M4, after that point all bets are off. If the code does direct disk hardware access, you'll need a patched version to run from the M4.

My bad, I knew with vormax cpm that |EMS was needed but didnt think about it...
Though using EMS here just hangs the CPC+, there is a .COM in Tristam demo so if I am successful to use CPM I should be able to launch the game
