  1. Past hour
  2. Ya-EVERY time. More literally than I thought. Lol, don't say I didn't try to help! But THIS is how ya do it. DoggoneitL2bells.mp4
  3. Another benefit of an SIO2PC device is the cost. It provides immediate access to the bulk of the Atari 8-bit library for a small investment. If you build one yourself -- which is pretty easy -- you can save even more. I'd like to see the SIO2PC concept extended to include the cart port some day; then cartridges could be added to complete the list of media available. I'd also like to see a PBI/ECI port to PC device; then something like a virtual 1090 application could be run from the PC, giving the capability to provide all devices in software instead of needing to create all this expensive hardware.
  4. I know... :^\ I saw a few things in there that I'd like to have, myself, but I can't get anywhere near him before he has to move. :^(
  5. Catch my files - they are correct and were tested. Eagle CAD needed to open. In this project I was using 39SF010 because I was thinking I would be able to put all E0 roms there. But unfortunately this cart uses different "hotspot" so we have only two games So You can change 39SF010 to smaller and cheap 27C256 and You don't need rotary switch - You can use two-position switch for two games. It fits to Sikor's plastic cases. Probably edge connector should be 3mm shorter, because when it is so long it will not open trapdor in some Atari consoles (fat). And pay attention to R1 resistor (1k). Not works without it. Probably new TTL chips don't like floating pins. 2600 Sikor E0.brd 2600 Sikor E0.sch
  6. It is not forbidden to release a ROM for free which contains IP, right? So you should be prepared for two versions, a PacLine ROM and a "Catwalk" cart binary.
  7. Make sure to get mommy's permission before you get a seller's hopes up!
  8. Except for certain goofballs that are wrong in every statement they make saying it doesn't use or show the Jag's full power Fumes and all.
  9. The jump forward/back is just a straight line up, then up+over, then over, then over+down, then down. Basically 5 straight lines approximating the arch as closely as possible. This saves a lot of memory and allows for just simple intergers. The delay on arching jump- just a variable counter that decides how long to move up, then up plus over, then over plus down, etc.. There is also a separate variable to delay the up/down jump. The frames are ALMOST as many as in MK2 on Genesis. But not quite, so to make up for lack of frames and telegraphic, the punch (for eg) will instantly appear out but damage is delayed a split second so irlt can be blocked.
  10. I have this game and each version of the Blue box....your manual price is on target...I have only seen a few pop up over the last 10 years...the average price sold is $1800 to $3500.... I know the person with the $3500 copy...the price is a little high but that is a good range in 2024..who know maybe more..not many in circulation..
  11. I took some picture of a real Atari Black VCS Joystick, I took it apart and you can see it has a pole in the middle of it and a hole though its pcb so why its a accurate joystick, RGL made the CXSTICK to much like THEC64 RED Joystick, they should of just copied the original Atari joystick and it would worked OK or did it like PLAION did with the Atari2600 Plus do not see why they didn't, they work together to make these. Atari Black VCS 2600 Joystick Teardown ========================== The good old days how things where built... a 80s joystick, I think it might of been made for the Darth Vader VCS, not sure when that come out, in the 80s maybe between 1980/82.
  12. While I fully agree there are better solutions, and your idea has some merit, it wouldn't be compatible with a lot of software. (Some, modern, upgrades also use $D380 as an address, so there's another compatibility problem.) Another option, would be to use PBI addresses. In such a case, enormous amounts of memory could be accessed. Sadly, such a solution wouldn't be compatible either.
  13. Got back from the cardiologist, I'm officially 56 pounds lighter since last June 29th, everything is A-OK. I have to go back in six months they want to do an ultrasound on my heart just to be safe but there's nothing going on, he couldn't be more pleased with my progress. They also want blood work for a cholesterol check but that will be low too, the last time I had it checked in December it was 158. This is the best I have felt in 10 years, I can't wait to get to Las Vegas in July to bowl Nationals and see my guys. After that hoping to make Portland this year. As always thank you all for your support.
  14. Enough good cannot be said about JagStudio. It’s the 🐝 🐝 knees!

    As you shared this, I just looked on the machine, my childs got @easter... and, yes, it states "made in Hong Hong", too 😁
  16. 55 downloads of the ZIP and nobody really commenting. I guess it either works, it sucks, or people are busy???
  17. Flash... You don't need to defend yourself in detail why or why not you are doing the Multitasking OS thingy... At revision 2024 I had a longer chat with Jac! And the CPC multitasking OS closer and played around little bit on the CPC standing on the desk. Nice one like it. But it's always kind of chicken egg issue with those OS?
  18. Very nicely done! I love the sprite work. I've had a pipe dream for a while now to make a samurai game but wasn't sure if the single button controller was enough to map all the combat moves I wanted to include (basic stuff like block/attack up and down plus jump and crouch). If you don't mind me asking, how did you decide on the control scheme? How many frames does each animation last and what kind of a delay did you institute for the jump forward/back feature?
  19. I remember this was a PIA - Win10 keeps complaining my disk is of GPT type and cant install, however Linux terlls me I have an MBR file system type on my SSD

    hahha.... yea, I sent Atari a mention of that yesterday...just in case it was a mistake.
  21. yes, the details may have been unique at the precise year of release, but by the time I read about it (…never came across it in the stores …) I had Streets of Rage 2 for Genesis, where you can throw, hurdle, smash…everything but hang from a lamp-post and kick back-forth. Now, Ninja Gaiden is one my favourite Lynx titles, - one I hope to beat (what-pun-there) without save-states. As for the Lynx alone; the problem was that it didn’t have any ‘crowd’ of any genre in the first place. But I find the quality of the Lynx games to be overall good. A few outstanding, brilliant ones, lots of good stuff, a few dreck titles. Just too few games. Cluncky; yes. I didn’t care overmuch, when you got backlit screen and superscaler graphics. Battery life and expenses: definitly a headache.

  23. Is there really any reason to not allow a Pascal-related question to have its own thread? I figured combining this thread with another thread would clutter the other thread with various questions, and would attempt to use that thread as a sub-sub-forum.
  24. Brought to you by the same people who tell guys who like certain bodies types to "touch grass" and "get a real girlfriend."

    I can’t wait to see what cars are available 🙄.
  26. Replying to an old topic here (I just joined the forum) but maybe someone finds this information useful. On an 800XL, I would not use PB0, PB1 or PB7. Ports PB2-PB6 go nowhere in the 800XL, its MMU does not know. There is no logic that inhibits e.g. turning the self-test rom on/off. Disabling "everything" by pulling REF low on the PBI will work, I still would not be doing it on my old hardware. If that kind of "abuse" would someday kill my ANTIC, I'd be terribly sorry. Anyway, so we use PB4 to enable bank switching. Which leaves PB2, PB3, PB5, PB6 in Rambo mode for a total of 16 RAM pages. Or 8 RAM pages (not using PB5) when running in Compy mode. So this is how we can implement many more RAM pages: Lets assume Rambo mode, so there are the first 4 bits (PB2, PB3, PB5, PB6) to select RAM pages. The PIA resides at addresses 0xD300 - 0xD303 (4 registers). But the chip select decoder does not decode all address bits. It only decodes the upper 8 address bits (A8-A15). So a valid PIA address looks like this (in binary): 10110011XXXXXXYY. Adress bits 0 and 1 (the 'Y' bits) are decoded by the PIA and decide which PIA register you are accessing. Address bits 2-7 (the 'X' bits) can be anything, you always reach the PIA. So on a PBI memory expansion you would have to implement some logic to "record the data bus" when the CPU writes to 0xD301. That way you know what the contents of (PB2, PB3, PB4, PB5, PB6) are. But if you change the "recording" to address (in binary) 10110011XXXXXX01, you can catch the write on all 64 valid addresses. Now also record address bits 2-7 when you record the data bus. You end up with 10 bits total, 6 bits from the address bus (A2-A7) and 4 bits from the data bus (PB2, PB3, PB5, PB6). That gives you 10 bits for selecting memory pages. Bingo, 10 bits equal 1024 pages 16 kByte each for a total of 16 MByte of extended RAM. Existing software which only knows about the 130XE will be able to access 4 pages of ram. Software that knows Compy expansions will be able to use 8 pages. 16 pages in Rambo mode. 1024 pages if you use all the possible addresses to reach the PIA. Hope this explains a bit how big expansions can work without compatibility problems. Baer
