Re: ULA, bus conflicts and the expansion devices

Could this be the reason why we detected that some Orics not working with cumulus, solved the issue when changing the ULA? We even started gathering info about which ULAs seemed to work and which didn't, but never reached any conclusion. At first it seemed that more modern ULAs worked better, but in...

Re: Loading tape games from disk

In this particular case, I was considering if it would be possible to store the original Encounter game on the floppy, so people could do like what I did for The Hobbit: The possibility to launch the original game as well as the new game, from the same floppy. Maybe I miss understood something, but...

Re: Loading tape games from disk

I wonder what's the format of the snapshots. No really fixed structure, it's more like kind of 'serialize' - here is the start of the 'save' code and the 'load' follows it. It's really easy to extract parts of it like pages 0,1,2,4 and others. More challenging is to restore VIA/AY status but yeah, ...

Re: Loading tape games from disk

This is something I always wanted to have: a way to put tape programs in a disk with no issues with multiparts, etc. I always thought the easiest thing would be use snapshots and proceed the same way an emulator does. It should be possible to store snapshots on disk and use the 16K overlay to set ev...

Maybe a false positive result?

Re: No operating system on disc

It can also occur if the disk is damaged (or the disk unit or even the controller itself!, but the latter most often simply hangs the machine)

Re: Multi-Key Handling

Great article Dbug!

You suggested me this method years ago and it works so well I've been using it since :)

I even had a demo, but was not as nice as this one, which showed just a matrix of 0s and 1s (1s for the keys being pressed).

It was indeed a smart idea!

Re: OSDK .tap takes a bit too long to load ..

If I recall correctly it is not related to unused areas, but to the important overhead needed by the C code (managing the stack frame, params, type handling..) plus the size of the libraries that the code uses... although I think a lot of effort was put to reduce them to the minimum.

Re: Oric.org updates

I had that game back then (always loaded with errors, so sometimes crashed in the middle of a game session). It was quite slow. I always wondered how a "revamped" version with hi-res graphics and colors and written in machine code (or at least, C) would look and play like :)
