NightSprinter Posted May 21, 2006 Share Posted May 21, 2006 (edited) Just as the topic asks. Because I'm contemplating just getting an Atari400 due to the fact my Demon Attack cartridge refuses to boot (yay for incompatibility with XL/XE systems..). If there's a lot that requires the extra memory, I'll go with the 800 instead. Edited May 31, 2006 by NightSprinter Quote Link to comment Share on other sites More sharing options...
Rybags Posted May 21, 2006 Share Posted May 21, 2006 Very few. Why not just get a disk-based version? Quote Link to comment Share on other sites More sharing options...
NightSprinter Posted May 21, 2006 Author Share Posted May 21, 2006 Mostly due to the fact I've no disk drive for my XEGS. Quote Link to comment Share on other sites More sharing options...
Bryan Posted May 21, 2006 Share Posted May 21, 2006 I don't know of any that do. A 16K cart will drop the system to 32K anyway (since the cart overlaps 16K of RAM). -Bry Quote Link to comment Share on other sites More sharing options...
bjk7382 Posted May 21, 2006 Share Posted May 21, 2006 You could also get an SIO2PC adapter from Atarimax.com and play ALL the games including Demon Attack. (well not all of them, but a couple thousand ) Quote Link to comment Share on other sites More sharing options...
Rybags Posted May 21, 2006 Share Posted May 21, 2006 Fixed Demon Attack ROM, will now work properly on XL/XE (in the emulators), and, and XEX file which will work on any 48K+ machine (binary load from DOS or use menu loader): demon_fixed.zip The cartridge has some code that "self-destructs" a RAM-loaded image, so I "fixed" it. Fixed incompatible with the XL (had illegal calls to $E7D1, instead of using the proper VBV routine call at $E45F) Quote Link to comment Share on other sites More sharing options...

Rybags Posted May 21, 2006 Share Posted May 21, 2006 That game looks like an almost straight port from the 2600. The self-destruct code was fairly easy to spot and remove. It's only a 4K cart so the XEX would load fairly quickly on a 1050. Maybe we should start a thread for fixing games which have incompatibility issues - most fixes are fairly simple. Also, a lot of cart images probably won't work if RAM-loaded since the copy protection is still in place. Quote Link to comment Share on other sites More sharing options...
Wrathchild Posted May 21, 2006 Share Posted May 21, 2006 A few were done on this thread, mostly there aren't too many titles incompatible, but if someone finds one and just posts it as a new thread then people here are sure to pick it up fairly quickly. http://www.atariage.com/forums/index.php?showtopic=32830 I'd hazard a guess that NightSprinter more or less would like a kind soul to take the XL ROM image and blow it to a PROM to replace the one in his cart? I don't think my Willem programmer goes down to chips that small though. Regards, Mark Quote Link to comment Share on other sites More sharing options...
Almost Rice Posted May 21, 2006 Share Posted May 21, 2006 Mostly due to the fact I've no disk drive for my XEGS. That seems like overkill just to play one game. It may be more useful to get the APE Warp+ multiple OS. I guess I think that way since I already have a 400. PM me if you still want a 400.

deathtrappomegranate Posted May 28, 2006 Share Posted May 28, 2006 I'm presuming that the original question was about 400/800 only carts, since the OP appears to have an XL system already. I can't think of any carts that require an OS-A/B machine that need 48K to run. IIRC, only the XE-labelled releases need that kind of memory, and some of those need 64K. All will run on XL machines anyhow. I believe that some Video 61 games also need 48 or 64K, but I don't collect them, so I'm not really very interested.

NightSprinter Posted May 29, 2006 Author Share Posted May 29, 2006 Yes, you do have that correct. I was asking as I was pondering getting an Atari 400 for all my OSA/B and 4-8 player games while my XE was for all the new games. I asked if there were any that would need the full 48k on the 800 in case that would make owning the 400 not worth it. Quote Link to comment Share on other sites More sharing options...
deathtrappomegranate Posted May 29, 2006 Share Posted May 29, 2006 In that case, I don't think that you need the extra RAM. I can't think of any carts that need 48K or more that won't run on the XE. However, most people prefer the 800's keyboard to that on the 400. I quite like the 400 keyboard, but I'm in a minority. Of course, it's also possible to get a 400 with more than the standard 8/16K of RAM. The situation is very different when it comes to disk- and cassette-based games, though. Many of them require additional RAM, beyond the standard 8/16K. Quote Link to comment Share on other sites More sharing options...
NightSprinter Posted May 31, 2006 Author Share Posted May 31, 2006 Well, turns out I found a disk game that requires an Atari 800 (or expanded 400): the DataSoft version if DigDug. Just curious, can one still acquire what is needed to expand the memory of an Atari400 to 48k (I'm still interested in the 400, Almost Rice, so lemme know when you find and test it)? Just a curiosity. Quote Link to comment Share on other sites More sharing options...

Just a curiosity. Yes, many disk and cassette games require 32K or 48K. Memory expansion cards for the 400/800 appear on ebay quite often, and don't usually fetch very high prices.

NightSprinter Posted June 1, 2006 Author Share Posted June 1, 2006 So, how difficult is it to upgrade the 400's memory compared to the 800? I know that you can just lift the cover to expose the cartridge and memory slots on the 800, but last I saw for a 400 only a cartridge slot was revealed.

I think you can still get the upgrade from Best or B&C Computervisions. Its a slot internal to the system. You replace the 16k slot with a 48k one.
