Re: New Database Model ZXDB

I think the one that got a built-in preview was an Excel spreadsheet stored in Google Drive. Maybe it doesn't work for Google Docs spreadsheets.

Re: Using TR-DOS software on real hardware +2e, DIVMMC

A game using TR-DOS doesn't imply it's designed for Russian machines like the Pentagon, and many such games aren't. In fact TR-DOS and the Beta disk system were developed in the UK.

Re: LEGO SEGA Arcade Machines

Those look really nice. And using a pistol as a joystick is quite clever. The other options are pretty good too, but I'd imagine the yellow sculpture would be a bit messy if the bricks are supposed to be falling out of it. Are the decals on the arcade machines all stickers, or just printed on? I use...

Re: New Database Model ZXDB

How about just changing the subject line of the post? It might be safer than modifying the post's contents.

Re: New Database Model ZXDB

I was sort of wondering the same thing about these bugfixes in general. I know ZXDB doesn't deal with loading screens (or does it?), but there was a report made about a wrong loading screen over a year ago and nothing happened since then ;) I guess the problem is related to what was brought up in th...

If one would turn off the music & sound effects, use all shortcuts, no safe strats and optimal movement I think it would be possible to get pretty close to 2 minutes.

Re: Counting T states in Excel

OK, I just found some basic instructions here:

Edit: I just read that apparently ticks does not support contention. So it may not be the best choice for accurate measurements.

Re: Counting T states in Excel

It depends what you're trying to optimise I suppose. If it's a sound loop that has to output at a very precise rate, or a graphics loop that has to complete before the raster overtakes it, then it is worth working out the exact execution times so you'll know whether it's fast enough or if something ...

Re: Counting T states in Excel

I'm pretty sure it would be possible. Since the machine behaviour is deterministic, you could just have another emulation running ahead of the main one that remembers the instruction timings. If it encountered a backwards jump to the current PC, it would just stop there until you get back to that po...
