Re: repaired games from bad tapes

Screaming Abdabs comes to mind. It has some standard blocks and then it switches to a custom loader with no standard block structure. Does it load on Mame? Yes, that custom loader works!. even the old TOSEC version that is corrupt with a few random hex [54] instead of [55] works??? here's another o...

Re: repaired games from bad tapes

I think that the Dragon really don’t care that much about a lot of things, and maybe it’s due to a flaw on Mame’s side. Yes, I would 100% say it's a MAME problem with the CAS reading routine. i don't know how to fix / rewrite the MAME code to read the tape loader correctly. but i know what it needs...

Re: repaired games from bad tapes

Fix for MAME only (it works in Xroar and most likely on real Hardware).
the CAS will not work in MAME as it will not load a BASIC file without a name or header.
it stopped with IO error at the loading pic.

i just put a blank filename and leader gap to make it work.

Re: Dragon Data logo in scalable vector format

opening the files with infranview, only shows a blocky lo-res thumbnail.
so i cleaned up what i could see.

the bigger logo, i sourced online.
This would make a good starting point to recreate a vector in newer software.

i do have access to portable version of corel draw x4.
PM if you want to try it.

Re: Dragon Composer / Composer Companion

i found a disk version of Composer.
which loads the Companion much easier and quicker.
not wait for music to end or pokes to enter.

RUN"BOOT.BAS"

.RUN"COMP.BIN" - loads the code that the Companion BASIC checks for and needs.
.RUN"LOADER.BIN" - companion boot file.

Re: MAME Emulation

I *think* there is still a small bug in the Dragon64 config. while using the converted AGD games by pser1. in MAME202 they only worked with this machine... TANODR64H. After you fixed the problem with the Dunjunz rom bank, some started to work with Dragon64. :) i think this is the correct behaviour f...

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...
