whant to do some amstrad plus carts and have issues

[Sebastian Blanco]

Hi after like 3 times ordering chips finally a couple of them arrived at my home 27C4001 eproms.I like to mod one of my cartridges to hold this kind of eprom follow the guide on the wiki is easy:

 27C4001  32   512K   LK6 (A15=A15=Address)  LK4 (A17=A17=Address)  LK2 (A18=A18=Address)
Just changed the jumpers like this i have done this before to use a 271001 (different jumpers and worked fine)

I like to use a rom i found some time ago can't remember where is called "cartuchos 10-11-16.rar"

inside several files like english)+amsdos+withmenu.cpr are in there

This roms claim to contain the basic amsdos and the hxc menu including several extras and this is very tempting for me so i don't have to load the hxc menu from disk.
The issue is that after burning the cpr file as a bin on my eprom burned and verifying ok the cart shows a black screen on the amstrad computer when power up.

Someone is familiar to this roms or have used them ?, also burning cpr files requiere any changes to them ?.

Here are the rom files:

This is the txt from the rom rar file:

Usage:

|c4cpc run cartridge loader(need c4cpc hardware).

|game load burning rubber

|hxc load floppy disk emulator software(need flopy emulator hardware. Options ,0 ,"a drive A ,1,"b drive b

|os load future os or symbos operating systems. |os to future os. ,string or ,0 or ,"symbos to load symbos ,1,"fdesk load future os with return to basic.

,"fver or ,"fhelp shows system information(from futureos).

|os,"cpm     cpm with 9 expansion rom. or |os,2

|os,"menu    This RSX command activates a menu system, which allows you to launch a .COM or .SUB file in an automatic way.
             An error message will be displayed if there is no .COM or .SUB file on disc.
             Else you can choose the file of choice with SPACE and start it with RETURN.
             Then the CP/M PLUS with RAM Disc will be started and the selected file will be launched.
             Attention: Some print routine are incompatible, for example this is the case for X-DDOS. Switch off on problems.


|os,"O       CP/M Plus is configurated for two drives and the RAM drive C: with 444 KB RAM.

|0s,"w       Probable this command is equal to RSX commands "|EMS" and "|O".(he made another thing buy i not know what)

All parameter admit capital letters.
Made by dragon for all amstrad cpc comunity.
Thanks to gerard(c4cpc),Norecess(hxc rom),podraton(symbos) to make these beautiful programs,and specially to TMF who modify the futureos roms specially for the cartridge and cpm expansion roms.

Hello,


You cannot simply change the file extension from .cpr to .bin


The .cpr files have a slightly different 'header' (I think that is correct).


Anyway, use the following file to convert between the two.
