I've not tried in emulation. It definitely works on real hardware - I've transferred dozens of floppies both directions as well as virtual floppies (ATRs, hosted on PC). I am not aware of any other way to get data onto a CP/M disk. Sparta DOS X has a CP/M driver, but it is still a read-only driver ta this point.

Yeah - the image viewer I currently am coding does just that - reads an 8bpp BPM file, reads in the palette, then displays the image in 256 colour mode at 320 pixel resolution. It's amazing just how good 320*[email protected] colour looks, especially on CRT. Even in 160 pixel resolution, that amount of colour is impressive.

What kind of talk? Things like "you little cuss"?

I made a 6 hour (one way) drive out to Toad computers, I think in 1996 to play a prototype version of Battlesphere. Found a typo in the game's opening text scroller and notified the team. Was a fun trip. I scored a working Ultra Pong for $5.

Limited colour palette on our machine causing this. If I were you, I would try editing the source image - turn down the saturation in the lower half of the image and see if that helps. There's definitely pre-processing that can help with this, but it's all experimenting.

I was never great at gaming, but some of these new releases make me really feel out of touch! It's is a great looking game however, very nice overall presentation.

That is all I was getting at when this started. I did not mean to drop such a bomb. Anyhow - when Stunt Car Racer came out, XBIOS was definitely locked to single SIO speed. All XXL had to do was tell me sometime in the time since then, XBIOS supported faster load speeds, and none of this huge blow up would have happened.

Bad day at work, 6 inches of solid ice in my driveway, uncontrollable IBS coming up on TEN YEARS NOW due to a surgery, and 3 more days of work this week before I can hunker down in freezing temps and do more of nothing. Sorry man. Imagine what my poor wife has to put up with. I'm gonna take my old man pills and go to bed now, so I can get up extra early and yell at some clouds

BTW - there is some weird kind of synchronicity going on here. I just converted this to A8, and did a worse job than someone when they did it back in 2015: https://atariage.com/forums/topic/200118-images-generated-by-rastaconverter/?do=findComment&comment=3147608

I dunno man - I'm getting a vibe here from some really prominent folks, that the only Ataris we should be supporting are 16kB CTIA machines. We don't want to use hi speed SIO loaders, we don't need PBI in the OS, we shouldn't fix an unbroken membrane keyboard. Don't need extra RAM - hey let's go back to the original 4kB and 8kB designations for the machines. Can't consider stereo pokey, that wasn't in the plans. Display options should definitely be limited to stock RF.

Something is clearly amiss. You must be part of the enemy, churning out those poxy machines with faulty mirrored addresses. I tell you on these quiet nights I can honestly hear RainMan himself, banging his head against the wall because register $D3xx repeats. Can you hear it - repeating over and over "yea, yeah, definitely a good coder, yeah, Dad let me drive the Buick. 16kB was enough, not gonna go to WalMart - yeah, yeah, yeah. Let's throw in an LAX here, that will do."

Damn - I see a competition coming up with the 8-bit (ANTIC/GTIA) folks. We pick fights all the time. We generally lose them. But we like to swing. So - um yeah, bring it All kidding aside - very nice looking stuff, I just got a DragonFly cart, so my real 7800 is going back on the shelf. Hope to see some of this on a real CRT soon.

Well, when Stunt Car Racer was released, the decision to use XBIOS was lamented because it only supported single speed SIO. So, when I asked about this earlier, in an attempt to gaslight me and make me look like an idiot (I need no help BTW - I do this fine all by myself) - a video magically was posted showing XBIOS loading at single and US Doubler speeds. Please - via show of hands. How many of you were privy to the fact, before me asking about this (AND APOLOGIZING BTW - when I admitted to not being correct in a statement) - that XBOIS loaded at more than 1X SIO speeds?

Well now, don't forget. There seems to be this issue at play: 1 - You or I say we have machines where something works - and we are basically told "fuck off - you are the exception". We are also dirty heathens that modified our machines. OMG - how dare we not conform to the original 1979 designs, as they were etched in stone, never to be changed. 2 - Other folks say something doesn't work, and whoa brother. Full stop. If they said it's broken, well then it's broken - they are meant to be hailed as gods, because their experience trumps all others. Example #1 - this very thread. More people demonstrated working hardware than did broken hardware. BUT - the broken hardware "wins" the argument at all costs. Change the argument, change the parameters, move the goalpost, etc.

Game says Parker Brothers. Is this not just an earlier version maybe? Either way - same blocky resolution (Mode 7) that emkay drools over.

Interesting - I was not aware. I like the Parker Brothers version, the music is good. Would have been nice to see them try a higher res version - it just looks so blocky and a tad slow after seeing the C64 version.

Fantastic work as usual! Man - those last 2 images damn near look like they were "hand pixelled" just for this machine.

Cygnus X I think - I only recently heard of it.

It would seem Antonia with 4MB is OK though. Also, non standard CPUs are also fine which is odd, given his penchant for using every un-documented opcode in existence just because he can.

What ever shall we do about those poor users who only use cassettes because that was the thing to do back then?

Everyone? Including U1MB users that were previously booby trapped? How sweet of you to keep such an open heart to all of us Atari users out there!

Good stuff - I apologize for misunderstanding the available load speeds XBIOS provides. I was under the impression that it was locked to 19,200. Seeing that it is not, I can withdraw my initial question. For the pokey 0 divisor, all I can offer is that I use APE with a USB device. I set the divisor to 0 on APE and any machine I use which has U1MB (for the PBI device to load a hi-speed SIO driver) will just chirp away.

I used Copy 2000 of course and APE USB device. It is known that the 1050 drive will not do divisor 0. However all the way back in 1987 when I installed a US doubler in my drive, my STOCK OS would do almost 3kB/sec. So - while I don't expect anyone with an actual floppy drive to read or write at divisor 0, you are not showing Prince of Persia loading from a floppy disc. You are loading fro a file hosted on the PC. So - load it with at least a pokey divisor of 8. This begs the question - why will you not answer a simple question? Why does XBIOS only support single speed SIO loads when software has supported higher speed loading for nearly 40 years now.

Any details on that?

No OS replacement (as in physical removal or opening the machine) is required. That's why we have PBI handlers. This was standard from Atari since 1984.
