  1. It always annoyed me that it was physically possible to to type merely 99.6% of the characters using control/inverse/escape sequences. I don't see why it shouldn't be possible to type it (e.g., with an escape sequence like [Esc][Return]). Has anyone tried patching the OS's E: handler to let us do it? >;-)
  2. I so rarely see the XMM801, which I had and used the heck out of (and finally learned binary, and could then make my own character sets on screen, thanks to the manual), back when i was a kid. Nostalgia kick
  3. This exactly the magic trick some of us used to create complicated BASIC 10-Liner contest entries. They ended up create an "EXTREM" category for such limit-busting submissions.
  4. Ooh ooh! Am I too late? If not: Bill Kendrick billkendrick Olympia, WA
  5. PS to get it to work on my The Ultimate SD Cart, I had to use the little "RomToCar" (html+JavaScript (!)) tool to convert the "atxbasic.bin" to a suitable "CAR" file. (Slightly different header, I guess?) Also, these PMG commands aren't in the online help, and also not noted under the list of non-Atari BASIC-compatible commands in the PDF docs. Oh, and listing the version # in the online help would be groovy.
  6. Discovering the Player/Missile Graphics commands, which are exciting. (Had never used BASIC XL before, but knew of it, thanks to Compute! books I had as a kid.) I'm realizing that PMG stuff gets turned off when the program ends (last line executed, or END issued). Makes it a bit hard to toy with things in immediate mode. Noticed that, e.g., "PMMOVE 0,100" results in an unexpected "Error- 30 ?Label at line NNN". So I guess "STOP" it is...
  7. Does AEB support bare "NEXT"s (no avar), like I recall TBXL supporting? (The docs don't show the avar being optional)
  8. I'm going through the doc PDF and it's excellent! (I've been wanting to try and go through and make a nice English doc for TurboBASIC XL; seems I don't need to!) I love that you've called out which keywords are from BASICs beyond Atari BASIC (e.g., "(AEB, TBLX)") I'd like to suggest you do that for some of the other concepts covered, e.g. hexadecimal aexp's, %0...%3, etc. Thanks for your consideration, and amazing work. I look forward to playing with it! (I'll try it on my Ultimate SD Cart tonight, if I have time.)
  9. H/t to Steve Boswell for sharing this thread on Twitter today. I somehow missed this, and it's right up my alley! Looking forward to toying with it, and perhaps using for my next set of BASIC 10-Liners
  10. A few random thoughts, after seeing a video Willie! (Arcade USA) posted the other day, and trying it via my Harmony cart just now... (and now my 7 year old is at it) As usual, this is an incredible piece of work! Well done, all of you! I'm super jealous that there's still not a good Galaga-style game for the Atari 8-bit computers When I first got a 7800, back in the mid-1990s, I had very few 7800 games for it, and Atari's 1984 Galaga was one of them. I was so disappointed with it, I ended up selling the 7800 to a friend. (I was gifted another one ~15 years later, and it's now my 2600 game workhorse ) -- Suffice it to say, your 2600 version is way better. Perhaps we'll one day see a "proper" Prosystem version!? My one niggle is that when I have dual-shot, I'm used to being able to hit two baddies next to each other, in their formation. (Based on my recollection of the arcade game, the (IMO) very good Nintendo NES port, and the PlayStation (original) version.) I wonder if the dual-shot bullets could be spread out a little, to account for the wider formation? I played Galaga a lot as a kid, in my local Safeway grocery store. Years later, I'd go to a local "laser tag" place, and play the arcade games they had there. (Don't think I ever did do the laser tag. ) I frequented that place with a couple friends of mine to play Tekken 2 (before it came out for PlayStation). (Marianne was expert at reversals with Michelle Chang; Thea always stuck to Anna Williams; I focused my button-mashing on Marshall Law.) Anyway, I discovered that days where I totally sucked at Tekken, I was awesome at Galaga. And vice-versa. There must be totally different parts of my brain dedicated to fighters vs. shooters. So... any thoughts on a Tekken port to the 2600?
  11. I've peeked at the YouTube video so far. It looks great! I definitely appreciate the use of double- and quad-width PMG sprites that I'm seeing!
  12. Michael asked me what firmware I have on my Ultimate Cart. I assume "the latest", since MacRorie just built it, and when I noticed the JTAG port on the back, he said "I can flash it when a new version comes out, if you want" (I'm fortunate to live about 15-20min away, though ) However, the menu program that comes up when I boot with the cart installed doesn't actually say! Is there a way to tell? Further, I noticed in Flashjazzcat's review of the Ultimate SD (sounds like he rewrote the menu program for Electrotrains) that you can drop a "_boot.rom" on your SD card, and the Ultimate Cart will boot the Atari into that, instead of the menu program built into the firmware. That's cool! Though my initial thought was "save a game as that file!", but that didn't work. Reading further, I guess I'm not surprised, since the firmware running on the FPGA maps some data into the ROM that the Atari uses (list of files on the SD card, etc.) Probably not something Pac-Man would appreciate, for example Are there any alternate menu ROMs out there to play with, or a way to sign up as a beta tester? (Sounds like simply dropping a file on the SD card to test, and deleting when you're done, is all that's needed, so seems safe enough.) So long story short: (1) is there a way to tell what firmware's running on the Ultimate Cart (I suppose, does the firmware make it visible to the menu program?), and (2) can I play with other menu ROMs?
  13. So how does one do this to the Summer Games (XE cart) ROM dump? My Ultimate Cart's reporting a similar error. I did a hexdump of the Mario Bros ROMs in this thread (non-working, vs the one you fixed up), and saw _one byte_ difference. I attempted to hack the same change in the SG dump, but to no avail. I have no idea what I'm doing, though. Is there a description of cart ROM headers out there that I could work off of? Or clues you give me? Thanks!!!
