Re: My new, compact Atari -> VGA adapter.

What's wrong with patching, say, the desktop resolution dialog and let the user choose appropriate resolution I think someone else is working on that, for use with this adapter ;) But as dhedberg pointed out, my approach will still have some utility. Have you looked at the overscan/lacescan drivers...

Re: My new, compact Atari -> VGA adapter.

Troed is still developing the software in that video, which is really tricky* and hijacks a bunch of TOS stuff :P It's my intention to have a shortlist of apps which work as they should, and hopefully then continue expanding.

Re: Atari Falcon advice

For anyone who just got a Falcon (€800-1200) I'm surprised that currently developed and supported software like HDDriver (€40) is considered expensive :/ It's well worth supporting.

Re: Perihelion tutorial #9 (overscan) problem

This is best explained by stating that the top border is never "removed" :) You can start the screen either at the 60Hz position, or the 50Hz position. The 60Hz position is earlier. What's known as a "removed top border" for 50Hz demo coders is simply a screen starting at the 60H...

Re: Perihelion tutorial #9 (overscan) problem

From what I understand the top border timing is pretty broad / forgiving, so I would have assumed that this one at least would work? They're almost the same ;) The check is done at cycle 502 on the line before first new graphics line you can create this way - and you only need to be in 60Hz over th...

Re: Perihelion tutorial #9 (overscan) problem

The most common cause for bitplane errors in the lower border when removing it is due to either going to 60Hz too early, thus doing a 60Hz line end (one word less) or staying in 60Hz for too long on the next line thus doing a 60Hz line start (one additional word).

Re: My new, compact Atari -> VGA adapter.

EmuTOS guys are currently discussing possibility to enable transparent mode switing within EmuTOS itself, if they decide to do so, even a passive DIN13_2_VGA converters and dual mode cables will work this way. Not sure what you mean with passive. The actual pins in the monitor port used are differe...

Wonder if the max #lines isn't 283. :) Supposing the limits are reached. 283 is indeed correct for the number of lines you get in 50Hz with DE constantly enabled, like with these hardware mods. In this case, software controlled overscan can go even further. I ... actually just broke a new ST record...

From your description it sounds like you've installed ad-malware. They can seldom be found in the official Play Store, usually they come with apps sideloaded (installed from untrusted sources), a setting you have to manually enable.

Re: Inquiry about 'generated sprites' techniques used on the ST and the Falcon

On the ST, the most limiting factor is that there are only bitplane modes available. You're unable to address a single pixel in any effective way, and while there are some tricks to address blocks of 8 through the movep instruction, most code simply works on 16 pixel (word) boundaries. Most sprite c...

Re: Hardware Overscan

Yes, but more importantly on this topic, there's no BLANK limitation for monochrome hardware overscan. 100 bytes are fetched, which means that 800 pixels are "displayed". That's indeed a perfect match with the number of cycles on a scanline minus the ones where HSYNC is active. 224-(212-1...
