Hopefully there will be a writeup explaining some of how it's done like there is for https://www.linusakesson.net/scene/a-mind-is-born/index.php You are allowed to call system APIs and firmware so I wonder if they base the geometry on some predictable blob of data somewhere or if it's all self contained in those 256 bytes. Computers are really good at recursion!

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.

Demos can cheat in all kinds of ways that games can’t.

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.

Aw heck someone was asking about the money cheat for Ghostbusters. Was it LM and LM102030?

Coffee Jones posted:Revision Demoparty 2024 was this easter weekend in Saarbrücken, Germany - and it seems they're better about putting video coverage online That team certainly did their best to make it sound like a C64! 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.

Raspberry Pis and FPGAs are the most boring thing you can put in a computre. Basically a fedora for your hardware.

Old processors are cool and good. Just emulate the whole machine if you’re gonna emulate the CPU

You Am I posted:Tidy looking 1200. Are you planning on putting a PiStorm32 into it? Nha, just a cf ide adapter and some fastram. Considered internal gotek but it looked ugly so will 3dprint an enclosure and hook that up as a secondary floppy drive.

Did they ever make a Gotek that uses SD cards instead of USB storage? That would help a lot on the ugliness.

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.

falz posted:Hoping someone here ran in to this - the CMOS battery is dead on my mobo, it's an "Odin OEC12C887A" It's this one Following up with myself with a different non physical idea. 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.
