BR programs recovery

Post by roo1234 »

Hello all,

I`ve been trying to recover some programs from old tapes and had success in some. There are a couple of programs that I still had no success, I wonder if someone from here could take a look and maybe help.

These are 2 brazilian localization games from Microdigital, probably for 2Kb machines. There are no online copies of those (Demolidor and Marciano).

I found a pic of the cassette, the one on the right:

I`ve uploaded 3 wav files in my Drive, 2 distinct copies of Marciano and 1 of Demolidor.

Here are the converted programs, the "Demolidor" must be run at 60Hz (NTSC), but in the EightyOne emulator the screen is shifted to the left.

Both would run at 2Kb, but interestingly they were saved with the entire screen file, without compression, so you need more memory to load them.

Marciano.p

I don't know the origin of the game "Marciano", but "Demolidor" is Macronics's Breakout: http://www.fruitcake.plus.com/Sinclair/ ... eakout.htm

This is great!
Yes, I probably loaded them and saved with my 16k expansion on, so there may be some extra stuff.
I wish I had copies of Tutor and Calendario...

I also have some recordings made with Ringo, higher speed. I tried them in eightyone which emulates it but I had success in only 2 dumb test programs. Some others are already converted (labirinto, mt, rl) so not worth the effort. A few I could not figure out, do you think it's worth trying to recover?

I have identified the remaining ringo programs and they are from engesoft zorbax tape.
So, not worth working on them since you already have that in your page.
