Re: Copper Demo

Oh, and you should use an older-style non-multisync VGA monitor, as the rapid timing fluctuations will confused most multi-sync monitors and they'll try to keep auto-switching/adjusting. I bet that's why Galaxian kept f*cking up all my VGA monitors except one old fixed-frequency display. On …

The C128 almost certainly was capable of displaying AGI graphics with its Video Display Controller (as opposed to the VIC-II included for C64 compatibility) exactly as they would have appeared on an IBM PC with EGA or Tandy 1000. Unfortunately, the chicken and egg issue doomed substantial gaming …

I have never found any Apple II game that stated it required an Enhanced //e as opposed to a IIe with 128K. Maybe only applications used it. While the Quicksilver Software ports are true booters, they still use a cut down version of DOS to a certain extent. The directory structure with the Bad …

Re: Conquest (1983) - Illegal Unhandled Interrupt

Some booter DOS conversions are picky and only run if you do a clean boot with no drivers/TSRs loaded or else need to be in the first 64k. I know that Frogger II, Gremlins, and Agent USA are like this. Agent USA wouldn't run on my XT with DOS 3.30, but it worked when I booted the computer with a DOS …

If you want to talk about being cruel, try Ultima II or III. In those games, the instant your character dies, the game will write that to your save disk. So you need one disk as your "master save" and many "slave save" disks. In Wizardry, you have to be continually deleting and recreating …

In the PC version of Adventure in Serenia, you have to use the in-game FORMAT DISK command, page 10 of the manual. See here (great site) http://www.mocagh.org/loadpage.php?getgame=serenia Ok cool. Now someone just needs to find that elusive KQ1 booter manual. EDIT: Never mind. I just noticed it was …

For the KQ1 PCjr. and Tandy versions, according to the manual/reference card you use the command COPY DISK, which as you say is a play disk. Demonlord probably cracked a play disk, as the master disk may not have a write enable notch. The disks for KQ1 PCjr, KQ2 and Serenia do not. http:// …

King's Quest (I) does not require a separate save disk. More correctly, Demonlord's cracked images don't as the unmodified game makes a duplicate of itself that you play off of and save to. This applies to the IBM version only since apparently the Tandy KQ does let you save on the original disk. …

I wonder what the 640x200 graphics would look like with the color on? Some games, particular ones that weren't designed with composite support, do some pretty funny stuff. One example is Double Dragon which alternates between the CRW and RGY palettes. If you played it on a composite display, half …

The IIgs runs at 2.8MHz or 1.02MHz, accelerators were always in demand for the machine. Right...they intentionally crippled the IIgs to prevent it from stealing Mac sales since it was in most other regards a more advanced machine (the Macs at this time lacked color graphics, expansion slots, a …

The Sierra AGI Apple II ports do not require a 65C02, and I do not know of any games that require it to use the Double High-Resolution Mode of the Apple IIe/IIc. It only would speed up software that used it. The Double High-Resolution Mode and 128K were introduced in the Apple IIe, before the Apple …

Flight sims were better on the PC, because of the comparatively large amounts of RAM available, and the speed of hardware floating point arithmetic if you had an 8087/80287 I'm not well-versed in flight sims, but did any actually support the x87? I was sure that no games performed floating-point …

I'd be very surprised if the PC's game market domination really started that early... not that I've seen any figures, but I don't believe this happened until 1990 or so, when the PC was winning over the home market and starting to offer clearly superior capabilities in terms of graphics and sound. …

OK - I take that back: I just noticed that a few Hi-Res adventures were indeed ported to the C64. Sierra made a lot of arcade and adventure games for the Atari 800, C64, and VIC-20 in 82-84, but afterwards essentially withdrew from the 8-bit market to focus on PCs. The only exception was the Apple …

Perhaps all those the money Sierra wasted on cartridges for the Atari and Commodore computers soured it on further development for those systems. You mean stuff like BC and Oil's Well. They found a niche in the IBM PC market that was not well-served by other companies. Perhaps so. Sierra had fully …

Maybe no AGI games were ported to the C64, but at least one C64 game, Donald Duck's Playground, was ported to the AGI engine. Yes it was originally written on the C64 in straight assembly language and the other versions (Apple II, PC, Amiga) were done with the AGI engine. Curiously, a version also …

None of the AGI games were ported to the Commodore 64 although it certainly should be possible from a technical standpoint. Especially since they had no apparent problem putting them on the Apple II, which was a lot more limited hardware in a number of ways. Anyone have any ideas as to why this was …

Not many sadly but I did see that there were some that had gaming channels on youtube but that place is different. I wish there was more people in general that enjoyed retro gaming that wasn't 30+ already. It does seem kind of odd in the sense that almost all the games can be downloaded and played …
