Sord (CGL) M5 Target

[jonesypeter]

Hi,

I'm trying to compile for the Sord M5, and am following the instructions here:

https://github.com/z88dk/z88dk/wiki/Platform---Sord-M5

My emulator is MAME, and I'm just using a very simple C program for testing:

Code: Select all

#include <stdio.h>

int main()
{
   printf("Hello CGL M5 World !\n");
   return 0;
}

If I use the following:

Code: Select all

zcc  +m5 -create-app  program.c

Then run with:

Code: Select all

mame -window m5 -cart1 roms\m5_cart\basic-i.bin -cart2 d:\test.rom

The code runs, but the emulated machine seems to constantly reset rather than stopping. Please see the following video:

If I use the options to create a tape file:

Code: Select all

zcc  +m5 -create-app -subtype=tape test.c

and use:

Code: Select all

mame -window m5 -cart1 roms\m5_cart\basic-i.bin -cass d:\test.cas

The program loads, then the emulated system seems to reset I have tried it as ROM1 (without BASIC) and ROM2 (with BASIC). Please see the following video:

Any idea what I'm doing wrong?

Thanks

Peter

Apologies, the link to the first video is incorrect. It should be:

I'm not going to comment on the tape side of things - I don't think I've ever got it working, so I'll defer to any advice from Stefano on that one.

The ROM side is actually working as expected - after main the ROM exits and is then restarted.

Since this is a bit limiting, I've added support for -pragma-define:CRT_ON_EXIT=XX to define the behaviour when main() returns - doc on this page: https://github.com/z88dk/z88dk/wiki/Classic--Pragmas

it's very long time I not using the wave mode on sord emulators, I remember it was tested on MAME and that the wave periods were incredibly short (high audio frequencies).
I need to test it again before confirming it's all right.

EDIT: I remember the Sord has different BASIC versions, could you try with BASIC-G (hope I remember the right name) ?

Hi everyone!
I used to be able to run my homebrew games on an emulated Sord M5.
This is no longer the case now. I have opened an issue on GitHub:
https://github.com/z88dk/z88dk/issues/2643
I have tried .was, .cas and rom with Takeda's emulator and Mame, with and without BASIC-I.

I am using these options (I need CONIO support):
"
m5: $(ASSETS_PATH)/z88dk_xchase.asm
$(Z88DK_PATH)$(MYZ88DK) +m5 $(SCCZ80_OPTS) \
$(INCLUDE_OPTS) -DEXTRA_TITLE \
-lm -create-app -Cz--audio -subtype=tape \
-pragma-define:REGISTER_SP=65000 \
-D__M5__ \
-clib=ansi -pragma-define:ansicolumns=32 \
...
-clib=default -pragma-redirect:fputc_cons=fputc_cons_generic \
...
$(FULL_FILES) \
-o$(BUILD_PATH)/X$(GAME_NAME)_$@.bin
rm -rf $(BUILD_PATH)/X$(GAME_NAME)_$@.bin
"

I am posting here to see if other people have recently managed to get something working for this target.

It does work with MESS 0.191...
It seems M5 emulation is broken in more recent MAME/MESS.
