Vic 20 was 30 years old when this port was written, now it's nearly 40, and we're still learning how to get the best from its hardware. Insane.

Some people might mock this but, in 1980, you'd have been absolutely blown away by graphics like these.

The fact that you can play and actually enjoy it says it all. This programmer deserves ALL of my respect!

I looooove seeing old hardware pushed to its limits like this!

This is very very impressive, but please remember just how expensive the largest official (32K ram) expansion would have been in 1980. Just off the top of my head at least 4 or 500 hundred dollars, so more than the computer itself. So pretty much no one would have been playing this in 1980 (esp families who needed a computer on a tight budget, and not something like an IBM PC- the 300 dollar price of the VIC 20 was a big reason it was the first home computer in the US to hit 1 million units sold) though they might have gotten a few thousand very profitable RAM orders if they advertised this game ahead of time. It easily would have been the most complicated and graphically impressive game ever created back in 1980!

For the Vic20, this is simply impressive. Nothing to complain here.

For the VIC 20 that is actually really impressive.

I don't really consider C64 Doom as a real C64 game because of all the hardware mods you need, but this just needs the extra ram so this is real.

Amazing Work Kweepa, I salute you! Thanks for showing NN

Arguably still not fair considering in 2016 using a 12 megabyte ROM is trivial (and even using something that vaguely resembles a 4 gigabyte fake CD drive isn't that hard). still, raycasting engines never cease to impress with what they seem able to run on...

That Doom music just sounds amazing on the vic20. Maybe because it mixes all my memories of together. The countless hours on a C64 with the countless hours later in Doom :)

Impressive. The sprites are strong with this one.

Neat, it looks like Predator-vision.

It's incredible just how far they are pushing some of the 8Bit systems, for more recent stuff people should check out the Spectrum version of Castlevania which is 128 only. I also covered the Jag version of Doom recently, I think out of all the official ports done its by far the best sadly it's missing music.

This is absolutely amazing

that looks shockingly playable. what a stunning piece of programming. i wonder if it was in assembly or directly in machine code now i gotta watch your C-64 vid had this been available back then, it would have RAKED in the money. on any platform of the time. EDIT: also, i think the music sounds kinda cool (for the VIC) ;) .. i so remember typing in programs from magazines and books with my buddy on his. we'd take turn typing and reading bug hunting was a bitch tho. tiny typos. .. and most of the programs weren't particularly ... impressive. even for the time. we had Apples ][e and TI 99/4a in school.

This is amazing!

There was a VIC-20 game called Capture the Flag with the same perspective. It came out in the early 1980s, and although it wasn't what you'd call a Doom game, it was impressive for the time.

heck I thought shrinking my 486sx 25 screen so that I could run it better was bad. This takes Doom to another level lol. Well nice effort I would say 👍

I love how you as a Brit say "It's far from a C64 and very far from a Speccie", implying the Spectrum was more of a powerhouse than a C64 which is of course only true for CPU speed. However, the dedicated chips inside the C64 made it a far more capable machine. I hear your "bias", Larry does it, Kim, Slope, and I love you all for your dedication to the Spectrum.

While I have the utmost respect for the role ZX Spectrum had in the home computing history, I must say that alleged great computational speed of Spectrum is a myth and rather modern one at that (it certainly postdates the year 2000). In the 80s no one, not even the most hard core Sinclair fans made any such wild claims. Probably because magazines were full of benchmarks that showed the relative speed of various home computers. Acorn BBC, IBM PC 5150 and such were at the top of the scale; C64, Apple II and Atari 800XL in the middle, while ZX Spectrum was all the way down, beating only his ZX80&ZX81 predecessors.

Great achievement.

Doom is essentially 2d data represented in a 3rd dimension. The simple trick is being able to do that in whatever method available. Technically we could do a game of doom based on the 'map' graphics and just allow the player to see all the enemies and items on that map. But the trick with doom was taking that 2d sector/linedef/vertex/etcetcetc data and putting it through an engine that presents it in the 3d FPS view we are all familiar with. If a sector is too high to be a 'step' it becomes a sort of one-way gate. Sector 'height' just makes a measure of how far you 'fall', but at the end of the day all of the data in doom can be represented in pure 2d format.

My grandad used to give me his computer when he got a new one so when he got a 64 I got his Vic20 and it had a motherboard where you could add extra ram packs. Completely pointless to me as there were never any games that used it but if this had been around in 1983 I would have played the shit out of it.

Vic 20 is the computer I deserve.

It would be Red and Black... I just haven't seen anyone try it yet.

fuck, it's pretty impressive indeed

This looks more playable than the 64 port you showed (unless it's the n64 port)

Check that beutiful music xD

From all the attempts to make wolfenstein or doom in 8bits, this is in some aspects the most impressive (even if it looks smaller and more ugly). While most engines raycast in square blocks (only 90 degrees walls) this one tried to have arbitrary wall linedefs, the only difference with real Doom is there are no different floor/ceiling heights, but it tried to mimick the original maps of Doom, like you got all the corridors and flattened the floors/ceiling to have the same value. He even mimicked sound fx from beeper, cheat codes, same secrets and traps, that's way more consistent for a doom "port" in 8bits than say Doom Spectrum.

man, imagine this in VR

damn, it really looks like hell
