An Asteroids arcade game implementation on an Spartan 3 FPGA. Display is an old scope tube with vector rendering, deflection by 12AX7 tubes. As seen on www.ct-lab.de
@gjc82071 Emulation, as understood by most people (referring to your MAME example) is a re-implementation of a piece of hardware, in software such that the "emulator" is able to execute an original piece of software code from the hardware.
To those who may not know. FPGA is not emulation, it is more like an exact recreation of the original hardware housed inside of a chip. For example, emulation is like having a person try to impersonate a celebrity, whereas FPGA is like taking an exact copy of the celebrity's brain and transplanting it into a "blank" person.
Fail comment. Look at the ghosting from when the gun isn't blanked fully, you can clearly see it's drawing vectors from all the different angles represented in the ghosting. Jaggies would be due to the D/A convertor resolution.
2 possibilities... A raster screen with a raster gun, or a raster screen with a vector gun. This is NOT an original vecor display, as vector display does not have ANY jaggies(which are clearly seen on the clock display.)
@mrt1r Cool/Thanks for the clarification. Anyway, I like & admire your scope tube setup. Have you tried any other vector type games on it? Also, is that a generic asteroids game, or the real thing? I love most vintage/retro technology that involves gaming. I'm a total "retroholic" & emulator man myself. With the exception of my (packed away) modest vintage consoles collection (16 consoles/200+ carts), I am strictly into emulation. I collect emulators/ROMs & have 50+/60,000+ respectively.
Hey! Very interesting project! I'm doing something very similar on a Spartan 3E board. I was wondering if you could point me in the direction of how to do vector graphics on a scope?
I was looking at buying a scope clock kit for an old valve scope I have but was hoping I would come across something like this too. Is the asteriods game fed from a soundcard of a computer or is it on a seperate chip? Is there a website with more information?
@bigshrimpn You over-simplify emulation a little. Emulation is a little more/better than that. Maybe like....taking the celebs exact twin brother & using him as the impersonator? I mean, MAME, it faithfully reproduces the games as near as exact as possible. You can't tell the difference in play/sound, graphic. All they are doing is running the game program on a faster chip. Unless, you mean strictly FPGA (I don't know what that is) & not ALL emulation in general?
Here is an example of total mastery of a CRT. :-) Nicely done.

this is mini Arcace
Jaggies are due to 8-Bit DA conversion, not 10 bit as on real asteroids mainboard.

reminds me of teh VECTREX
Why does this look like a raster display. Look at the jaggies when it is in clock mode

where do you get the scope display?
where to buy? :)
Yeah, why bother to learn and do something to improve your skills...
