I ve tried this. The problem with the 63kB TPA in CPM2  is that you loose all the firmware access.
No. Look at the TIMEROM source code to see how.

Use Dobbertin CP/M 2.2 version 1.4. It provides 63 KB TPA, 0,7 MB for B:, 444 KB RAM drive C: and even supports real time clocks (Dobbertin RTC, dxs RTC, LambdaSpeak RTC).

1/ CPM+   : ~ 61 KB of TPA but no access to banks (all used  by CPM) + firwmare acces
2/ CPM2.2 (standard) : only 39kB TPA but easy access to 64KB banks + firmware access
3/ CPM2.2 (extended TPA) : 63kB TPA, banks usage not documented, no firmware access without patch (if possible)...


For now I use the DK'Tronix version of CPM2 wich allow to swap from a standard TPA to an extended TPA. The best for my usage will be something like the CPM2 Dk'Troniks version + B: of 720KB and C: virtual drive (faster for compilation)

Thanks, But I already use this for CPM+ ;D It works fine with CPM+ but i need to use CPM2.2 here.

Use Dobbertin CP/M Plus. It has 0,7 MB Vortex format on B: and provides 444KB RAM disc on C:
It's somewhere on my homepage and I uploaded it here too.

Hi!


For a new project i need to use banks memory with CP/M on my CPC6128+. I took some time to see if it's possible to patch CPM+ (for example to have the memory block 3 for my own usage)  but it looks very complex and need to create a new CPM+ version. The better (anyway the simpliest ;)  way seems to use CPM2.2 for that, as CPM2.2 juste use the 0..3 blocks of memory.

But is it possible to have, like in CPM+, a CPM2.2 version with a B: drive of 720ko (or Gotek) and a virtual C: drive?

About CPM+, was there some attempts to reduce the memory footage on the CPC ? It looks like the CPM+ on the Amstrad CPC takes all the ram for its own usage with tons of buffers. Reading the Digital Research old documentation, the memory footprint could be much smaller.

I watched @Novabug live game testing last night which I enjoyed.

I don't always get chance to watch it live, but I enjoy watching it when I do.

Anyway, Novabug tested a game last night which I think would make a great two player game on the GX4000 so thought would get it sorted out.

Here is....

THE RACE

The game is now Joypads only.

Joypad 1 UP or DOWN to select one or two Players.
Console Pause Button to Pause, unpause.
Joypad Button 1 to Accelerate, Down to Brake, Button 2 for Turbo.
Use Console Pause Button or Joypad 2 to pass highscore table.

I've included a poked version with Infinte Time.
Totally unknown, like a lot of these budget games from Mastertronic, Player Premier, etc... Particularly in France. Thank you for the discover. The game seems to be fun, based on the Led Storm concept but for two players and without any other cars, just obstacles to avoid. Have you seen the explosion of the car is made with multiple '0" character?  ;D

Technical Support / Re: CPC 464 - very quiet speaker audio
« Last post by gw0udm on Yesterday at 21:00 »
Thanks - any particular likely culprits? There are a lot of small capacitors scattered around and they look OK but obviously difficult to conclude much from that.


I'm sure it's something with the electronics, I've checked the speaker and that looks fine but I resoldered everything for good measure.

Applications / Re: New customisable firmware (lower ROM).
« Last post by Duke on Yesterday at 20:33 »
Thanks, if it's the only mod, it makes sense!
It is.

For a ROM>15 I guess there is more work to do.
I don't think so, if you want to achieve the same as I do with the modified lowerrom (make games/programs that use firmware and re-init roms compatible). Just replace 6 with 31 and put M4 rom in slot 31, that should work I think.
