Sharp MZ

I'm not sure about the 80B but the 80A plastic screen has a couple of catches at the top (and I think at the bottom too), gently pressing down on the catches at the top means you can unhook the plastic and remove it. That's how I've cleaned mine in the past.

Ah, just seen your message, thanks :) I didn't realise $1194 is the tab counter. Hi, $1172 is part of the screen XY co-ordinates $1194 is the tab counter I think Ist listing is from the preloader 2nd listing is from the program that the preloader loads which load another header modifies it and then ...

OK. Here it is, Star Avenger in MZF format :) STAR AVENGER.zip I could not get it to work in the emulator with the -real- CMT header values in the main program file (i.e. all zeroes). I had to put the real values into the header even though the loader program modifies the CMT header and inserts the ...

I successfully rescued the complete game last night. However, the loading screen part failed to execute the main game. Very strange, so still more to work out on this one. I can load the main game on its own though (which you can't from the tape due to the primitive copy protection) because I altere...

Ok this is pretty interesting, different results from disassembling the loader when I do so on the MZ-700: Star Avenger Loader 700.png Pretty odd to suddenly have a different result than when I did this on the 80A. But this gets me a lot further, this is more like what I expected. This is priming th...

Well, I've just successfully loaded my original Star Avenger tape on my MZ-700 so I've proven my tape is good. I then decided to try and circumvent the 1st 'loader' program and only load the 2nd one. I got the same result as I did on my 80A in SuperTape, the MZ says it's loading a file called "...

The plot thickens. I just noticed this in the loader file's header (first file on the tape with the title screen in) residing in the comments field from $1108: Star Avenger Tape Header Comments.png Unsure what's going on now. It's an interesting puzzle. I probably shouldn't be trying to copy the tap...

For anyone interested, I disassembled the loader for Star Avenger: Star Avenger Disassemble.png The reason for this is that I think there is some sort of primitive copy protection happening with it. I have the original tape (finally a working one) now and was trying to read it into MZF Studio but on...

I'm planning on scanning all mine in (including OCR) for my website soon but it's going to take a while.
