Hi Guys. Are SRAM and CPU interchangeable between NTSC console and Pal Concole ? As I understand the STIC for sure is not interchangeable between PAL and NTSC

For those using the Docker image is there a documented procedure to upgrading or do I need to redploy and configure it again?

Running this one any longer would not have resulted in improvements. The final 100 million iterations only resulted in the normal distance changing by the thousandths. This was using 8192 solutions as well. I was surprised to get this one to turn out at all, without making some pretty drastic changes to the source image.

But what kind of resolution are these games running at ? I was also thinking of games you can directly compare to other 8 bit machines. Like Druid for example. It seems like a rather simple game graphics wise, yet the A8 and C64 versions look nothing alike. I understand the different capabilities in sprite generation but trees and background grass should be identical in the two machines. Zybex also. It is clear that Zybex on the A8 is using one color with many shade values (luminocities?) whilst the C64 uses different colors. Also the C64 seems to be in higher res. Does Altirra show you the native resolution the game is running on at any given moment somehow?

Yes I know, I have copies of his tapes as well.......

Hopefully final update coming: I have been able to do successful preliminary tests on the latest production ready pcbs. I want to do a few more intensive tests over the next day or two, but severe weather is moving in and I have to shut down my electronics. I plan to have a final proof of function Youtube video posted as well in the next day or so. Corrected gerbers, schematic and BOM should be up late Monday if all goes well.

Gary’s talked about this issue before. Here’s an interview from 2019 (jump to ~11:57 mark) where he discusses the topic.

Yeah, that seems reasonable. I would love to see a deconstruction or disassembly deep dive of the level... like I suspect it picks one of 2 or 3 patterns. i wonder if the repeating space is like a square or more like a circle, fundamentally (sort of like I'm still in awe of how 2600 Battlezone tracks even the offscreen world...

The main trick IIRC with it is you need to get a high voltage pulse on sync into the sync/reset line. I don't think the circuit is documented, only the concept... The datasheet I have backs up my memory -- you have to drive the RESET pin above 9V (Recommended is listed as 10-12V) for external sync. Which means you need to extract sync from the previous VDP's composite output (rated as 1.85-2.1V), raise it cleanly, and juggle it with the console reset line. Honestly the 9928's approach of just signaling an external video switch seems easier. That said, when I played with the video input line many, many years ago, I actually just cut the reset line (with the intent of figuring it out later) and fed in composite video from a VCR. Everything /worked/ technically, switching, overlay, but it was useless without the sync of course... When the 9918A was in charge, there was slight bleed-through from the VCR, out of sync of course. The balancing circuit would probably solve that. When I switched on external video from the VDP register, the VCR input took over sync and was stable, but without sync pulses, the VDP was now out of sync. It was clearly superimposed, though! Radio Electronics did an article on making a titler out of a 9918 and using the video overlay feature, so in theory all the needed information and circuitry are in there. I've saved the article all these decades out of interest of seeing it someday. Their job was a little more complex since they needed to take a slightly incompatible external video signal, but stacking VDPs you should be able to assume they are starting pretty damn close. (edit: All these years I've been sharing the wrong issues - turns out R-E did video titlers /twice/. The first was just for generating text screens. The SECOND was the TI-based overlay one. BUT... my brain remembered wrong (and young me in 1985 probably misunderstood)... it does use the 9928 and externally switches the video, it does not use the internal mixer. BUT, it still needs to generate that SYNC pulse, so there is still valuable info in here. Also, my archived scans are terrible quality...)

I just flashed up my latest build of 4 devkit's with 1.3! Thanks! I will be posting Atari Fujinet devkits and Sdrive Maxes on Ebay shortly. PM me if you want to work with me directly on a unit.

All the games work for me on Stella. I hope some other players have some suggestions for you.

My strategy for the tower tops is to continually steer in one direction, usually to the right. So when the round starts, I'll take out the first few towers directly in front of me, and then I'll begin steering toward the right. I'll continue shooting any towers that appear, while always going rightward the whole time. Unless my shots miss a tower or two, I will encounter enough towers using that method to get the bonus for clearing all towers.

Would be nice. I could be wrong, but would most likely have to replace the start app altogether. Someone implementing a replacement gui may want to utilize the space and graphics regions in an altogether different manner, especially for those that already have experience and existing code to work with.

Jed Margolin worked in coin op and his info came from VAX tapes as well.

According to this site, the game was released in August 1982 - https://www.randomterrain.com/atari-2600-memories-history-1982.html#donkey_kong It was even released earlier but had to be recalled because carts didn't work on the 6 switch models. So they had plenty of time to have the cartridge on the market and could have gone with 8K and a few more months of development.

New PPEB firmwares to test, mainly for @wiloson but also @chue and @RickyDean too. These are the 2MB SAMS and 8MB SAMS versions (8MB only for use on the v3 board, or piggybacked mod) but both are running at 250MHz and one NOP. You can now change the settings for these in autoload.cfg to increase them using a line saying "MHZ=252" up to 280, and "NOPS=2" up to 9. I've also cleaned up the speech PWM to use 32KHz refreshes instead of 16KHz (I'm far too old to hear 16KHz, but there was some 16KHz noise in test-recordings I had made in Audacity, and they are gone now - your pets and/or grandkids will be grateful).

I actually lost some progress earlier when I busted a FOR/NEXT loop, couldn't find the damn thing, and had to restart from a way too old back up copy. Ugh. UGGGGGH. But now has arrived the MYSTERY BYRON! Whack him with the PEEK-0 hammer for a bonus, higher than all other bonuses in the game and perhaps even double that. And gaze in awe at his iridescent green BONUS! sign! It looks nice... the VDP has some gross colors but it comes through on the shades of green. Next? Bombs! Hit them and be blown sky high! (But the program is already the size of many ColecoVision games and it's only 75% finished. I might not be able to make it as explicit as I wanted. I don't know what the overhead is on the compiler. These games go up to 32K, right, Nanochess? Is bank switching a concern, or is that handled auto-magically? whackem_game.rom

Now tcp support is in it's a pretty good time to update your tnfs server if you have one, especially if it's public.

Hello and welcome! The Sandisk card should be fine and good choice. I've also used "Microcenter" cards from Amazon with very few problems. I guess the mostl likely issue is you may not have re-formatted the card as a FAT32 filessytem? Most cards come out of the box formatted NTFS, but the Flashbacks won't recognize anything but FAT32.

Nintendo only changed the name of the Ultra N64 to the Nintendo 64. Dolphin and Revolution were code names and were never intended as definitive names. I know, it's technical. I just hate when a "4" or a "5" appears alone on the following line in a text, so I insert a non-breaking space BEFORE the number, which requires to select the space and type Alt+255 (on Windows at least). The point is to avoid this for instance: blah blah blah blah PlayStation 4 blah blah blah blah and get this instead: blah blah blah blah PlayStation 4 blah blah blah blah And in languages like French, we also have the same problem with punctuation, since we type spaces before quotes, colons, exclamation points, etc.

If you know how hardware works in great detail, yes. If you don't, no one seems to have constructed a suitable metaphor such that it can be communicated in a manner that results in a consensus, but that shouldn't prevent anyone from discussing it vociferously if the past 30 years of forum content are an indicator.

i wrote it on other topic but here is most relevant. its based on tchak909 and monsoft work before. Monsoft one was that i used to use before. I made a container version for x86 of TNFS server that support TCP. In case that anyone (besides me) want to use it on home lab server or NAS appliance. It's small - around 6MB container. https://hub.docker.com/r/zaqu/tnfs-tcp
