Detecting VBL on 800 in 700-mode

I have written a small program on the 700 that detects VBL by waiting for bit 7 on $e002 (8255 port C) to go low. This works well on the 700, but when I test this on an 800 emulator in 700-mode the code always returns immediately. How do I properly detect VBL on the 800?

Re: Some games for MZ-700

Great :) Is it OK if I upload these to the sharpmz.org website?

Btw I've been looking for Headache for quite some time, I used to play this back in the mid 80's.

Re: Dumping character ROM

Ok, it seems to be an emulator "feature".

Some authors have mirrored the bit combination in each column of the characters.

Dumping character ROM

I have an MZ-700 with a Swedish character ROM I want to dump. The ROM is a Mitsubishi M5L2732K, for which my EPROM programming software (MiniPro) does not have a profile for. I have tried to dump it with some other 2732 DIP24 profiles, and while it seems to work the bit-order appears to be reversed ...

MZ1200 for sale

I got an email from a gentleman in Australia that has what he describes as a pretty pristine, hardly used MZ1200 complete with manuals for sale. He's not a member here or in the fb groups, so if you're interested send me a mail (sharpmz@sharpmz.org) and I'll forward it to him.

Re: Générateur de caractères graphiques pour Sharp MZ-700 / PCG for Sharp MZ-700

Impressive! This opens up for a lot of possibilities for gaming on the 700. Without having looked into this at all - would it be possible to create a VBL interrupt too?

Re: sharpmz.no - problems

A table in the database was corrupted. Fortunately it was easy to fix once the problem was found, so it was not necessary to restore a backup.

Btw we have daily backups of both the site and forum databases, so in worst case a day of work/posts will be lost if something happens.
