Re: repaired games from bad tapes

repaired files on this music demo disk.
looks like Microvison put a auto boot loader on the disk after creation, which corrupted the CASCADES.BIN file.

The Pulser version is full of corrupted files and is missing the MENU.BAS and ENVELOPE.BIN.

This version is ok and has the boot loader intact.

Re: MAME Emulation

Yes, but now the ddos rom is mandatory and the system will not boot without it. I was under the impression Dragon Disk DOS was a EXTERNAL cartridge that connected the disk drives with a ribbon cable. The Dragon32 doesn't need that cart to load Cassettes. The dragon32 driver has specified dragon_fdc...

Re: MAME Emulation

with one of these NEW updates, the extension slot command-line got broken.

this used to boot the dragon32 machine without DDOS.
mame dragon32

and required this to turn it on.
mame dragon32 -ext dragon_fdc

it's always enabled now.

Re: MAME Emulation

Meanwhile, as you can compile it, I suggest you just copy the old palette values on top of the new ones and compile it again. Thnaks, i already recompiled it. I rolled back to MAME 208 (22 April) with the latest 2 fixes. which also has the incorrect NTSC artifacting on PAL machines. With old and ch...

Re: MAME Emulation

That’s how it’s supposed to look like. If you want to see the red-blue artifacting, start a Dragon Tano machine, which is ntsc. AH!, i see. I can't (don't want) to believe that WHITE is going to be darkish grey, and BLACK a weird shade of dark green as the MAME standard from now on. my eyesight is ...

Re: MAME Emulation

I've created a pull request to add my changes to MAME's source code: https://github.com/mamedev/mame/pull/4980 :ugeek: your sample pics look very nice. but when i recompile the latest source code from GITHUB, the artifacting looks broken. this is what i see now, and before... maybe i did something ...

Re: MAME Emulation

Finally solved! Problem is the default keymap/joystick settings MAME uses. even when the Joystick port is set to "Unconnected". to enable FIRE in LEFT joystick. you MUST enable RIGHT Joystick, and remap all controls to NONE. This testing also found another problem. SPACE seems to be disabled to star...

Re: MAME Emulation

just done further testing. recompiled MAME 202 with just Dragon and COCO2 machines. ***removed Joysticks from USB ports in PC. enable 2 joysticks in MAME config. remap keys for left analogue joystick (W,S,A,D,\). control works with both machines in left and right ports (using keyboard to control). t...

Re: MAME Emulation

I haven't looked at this yet but would be very surprised if there's an issue. The joystick implementation is shared with the coco machines, which have lots of users, so would've expected them to be submitting bug reports too. ok just done a little testing. MESS158 COCO2 - Left and Right Joystick mo...

Re: MAME Emulation

I can now confim, the Joystick code in MAME is definitely bugged. Caverns of Chaos with only the LEFT controller connected. keyboard must in emulated mode as it only uses "8" for the fire button. RIGHT FIRE is also mapped to "7" (and joystick button) when only the RIGHT Joystick is connected in othe...
