Looking at a few demos, they make a lot of use out of palette animation, playing to the hardware's strengths. Always wild to have demos that have effects on hardware that have no business doing what they do. Like this commodore PET demo providing "3d animations" by manipulating petscii - guess swapping out characters on a screen is very fast. https://www.youtube.com/watch?v=cznyKsOl3po I guess that's the same thing happening here in this C64 demo - petscii animation simulating voxels. Commercial games of the time never come close to the sheer style these demos have https://www.youtube.com/watch?v=L8onlB0F1_A&t=311s I keep forgetting how truly limited the apple II series was in the graphics department.

fixing up an amiga 1200 i bought to be a bit nicer Did a recap, installed a CF IDE adapter. Was meaning to put in a gotek, but found it ugly compared to the regular floppy so I'll rig up some external adapter for that instead.

Good show. One giveaway though: the NES sound chip doesn’t have a filtering component, so it can’t emulate the frequency filter sweeps that are common in SID music.

Dunno, this page has a pic that looks the same as it did in mine. https://www.retronerd.co.uk/product/amiga-600-gotek-drive-base/ Looks loving awful so reverted back to using a floppy drive. And I mean... being able to use actual floppies still is pretty neat, and I can always use an external gotek + internal hdd.

Anyone aware of BIOS hacks for old computers? I saw some for award bios (superior to ami in every way) Basically couldn't I hack the bios by flashing it with something that lets me bypass the "must enter bios with bad clock" screen? I realize this is a chicken egg problem but still curious. Even replacing bios with this is probably easier than replacing battery.

falz posted:Following up with myself with a different non physical idea. Both of those Necroware projects have identical function, the difference is how they're assembled but either would be installed in your machine the same way. If you buy any prebuilt Dallas RTC replacement you won't have to worry about those differences. For example: https://www.tindie.com/products/glitchwrks/gw-12887-1-dallas-ds12887-rtc-replacement-module/ If you wanted to replace your BIOS you'd need something to write an (E)EPROM as well as a compatible chip to write to, and of course a ROM image to write. It would be possible to hack a BIOS to not complain if the CMOS/RTC battery is dead and the memory erased/garbled, but consider that it usually stores more configuration than just the clock. You'd lose a lot of configurability for the system if you don't have a working CMOS/RTC. nielsm fucked around with this message at 19:24 on May 4, 2024 |

falz posted:Following up with myself with a different non physical idea. You can do a lot of wild stuff but you really have to be careful. You can just mod them yourself. I used "Award BIOS Editor" I think. There's a lot of documentation for specific BIOSes out there that would be worth reading if you wanted to do it. About 10 years ago I modded a bios on a laptop to enable some stuff. Somehow, some of the stuff I enabled that seemed completely unrelated to the keyboard or USB or any of that caused the keyboard and any other keyboard plugged in to just not work in Linux, communicating with the bios itself, and GRUB. It did work if it got into Windows though (don't remember how I figured that out) but I ended up trapped since I couldn't do anything with grub. I could have taken the harddrive out and put it in another computer and make GRUB boot into Windows, but what I did was grab a harddrive from a Windows laptop, toss it in, get into Windows and flash a clean BIOS. That was the last time I modded a BIOS. I guess the point of this is you probably can mod a BIOS yourself to maybe do what you want but here be dragons.

I'm having an issue getting an SD-to-IDE adapter to work on this AT board. It won't boot off a floppy if there's a partition on the SD card. If I wipe the SD card with diskpart it'll boot off the floppy and let me fdisk (and fdisk /mbr) it, but when I reboot it loads the floppy a bit and then hangs with the floppy light on. The drive type settings seem normal: Capacity: 8455 Mb Cylinders: 16383 Heads: 16 Sectors: 63 Anything I can try? I have a CF-to-IDE adapter in the mail. Maybe that'll work better.

How old is the BIOS on that board? Do you have any BIOS extensions (like XT-IDE) installed? Because that's a quite large disk to offer to a old hardware.

Alternatively, consider finding a SCSI adapter for your computer and get a BlueSCSI or ZuluSCSI device. They're very convenient and give you a ton of flexibility.

It’s dated 1994 and I can’t find any updates for this board. I can cut the capacity down I think. I guess I figured if the bios could auto detect that capacity it should’ve been fine.

Yep - it was that easy. I just manually set the cylinder count so it reflected ~2000 MB and everything worked great after that.

She lives! Still have a few things to do before I button it up, like replace the PSU with one that’s not 30 years old and see if I can figure out how to mount the power switch properly so I don’t need to finesse it to power on. Tiny Timbs fucked around with this message at 03:33 on May 12, 2024 |

Is there any reason to play the Amiga version (which I don't have) over the IBM PC version (which I have)? I have an Amiga 500 and have been thinking of actually doing something with it. But a lot of the times it boils down to "well it's actually as good or better on another system" or "it's too expensive". E: I don't think Cannon Fodder is particularly expensive, which is why I'm considering it.

3D Megadoodoo posted:Is there any reason to play the Amiga version (which I don't have) over the IBM PC version (which I have)? Generally the answer is no for VGA onwards. While a few games might have the odd bugs on PC or the insane color choices on Space Crusade for the most part there won't be many if any major differences. Possibly some 50 or 60hz shenanigans on ports to either PC or the 3 16 bit era consoles here and there ala the Genesis US Shadow of the Beast or Gods. But in general the Amiga 500 is in the same space as the C64 in that if you own one or two of the other bigger platforms of the era you can kind of skip the machine and not miss too much at all, especially given how the Amiga only sold 4.75 million machines according to Wikipedia. It was functionally nonexistent in most of the world. If you already have a machine or live in PAL regions they can be a fun project full of silly upgrades from Icomp.de and the like but if not? You can easily manage without one. And sorry if I seem to not keep up with my own thread but I do read it I just don't post much. I did add a thing by request a few weeks back. I've just been in a god awful place mentally and have a weird aversion to posting as I want like a sub .5 post per day average anyhow. But know I'm still here and around.

I recall some more games, like Lemmings 2, having more music, more samples etc on the Amiga. IBM compatibles just didn't have as good sound cards yet, for some time. By the time PC wavetable synthesis was commonplace, the Amiga was long dead as a format. If you're emulating, it comes down to whether you prefer low-res sampled 4-track tunes, or Soundblaster FM synthesis. (If you're playing Lemmings 2, don't forget to add 1 MB of chip memory to get the extended samples.) As for graphics, as was stated, PC EGA looks worse than Amiga's 32 colors, usually, so you might prefer the Amiga version of some older stuff. But I can't think of any good examples.

Speaking of Amiga, finally finished my CD32 setup. Did a full recap, put a Terriblefire 330 in it + Compact flash drive. Works wonderfully now. Hard to argue against CD32 as a gaming Amiga.  Screen is currently mirrored across the monitors. Will probably move the LCD elsewhere and just use the CRT on this desk later.

I could swear I owned a copy of Lemmings but I couldn't find it anywhere last night. Not like the game's rare, it's just a weird lack of Lemmings. e: Actually after posting that it occurred to me I might've confused it with Worms, which I do have in abundance.
