Re: MZ 700 - detect PAL/NTSC

Anyway, I agree something is still fishy with counter1. I will check it on my MZ-700 with Unicard. ^^

Re: MZ 700 - detect PAL/NTSC

Emulator: I'm not expecting the emulator to run each instruction at an accurate 3.57 MHz frequency. An emulator tends to run a batch of instructions then pause to make the overall speed close to the simulated frequency. So you may not capture the counter value at the right time. Hardware: Was it a t...

I guess you wrap it with

Code: Select all

Re: MZ 700 - detect PAL/NTSC

Well remind me on FB that I should try a code to count /BLNK events in a frame on my MZ-700 this weekend.

Re: Dumping character ROM

Ok, it seems to be an emulator "feature". https://www.sharpmz.no/articles/the-mz-series/mz-700/mz-700-the-character-generators-rom/ Some authors have mirrored the bit combination in each column of the characters. Are they Japanese? could be a trick to not publish the original font file as such...

Re: Dumping character ROM

I'm not sure the Swedish font was an official one and was fully qualified. It is probably a third-party selling MZ-700 with a Swedish keyboard and a monitor rom and a font rom they altered.

Re: [MZF] MZ7: MZF file compressor using ZX7 algorithms

Ok, the point for MZ7C is to allow loading MZF or WAV files not involving any special hardware like Arduino: it should work for genuine tape.
I agree with using the keyboard buffer to decompress because it appears to be working for any MZ serie K. So it should be an option to add to mz7c.
