AVR console with vector display!

This is something absolutely awesome, and even quite on-topic! https://www.youtube.com/watch?v=dTGOEe8f8ls https://mitxela.com/projects/console An ATMega128, most notably producing a vector display on an oscilloscope! But the audio solution seems to be pretty neat as well, with a bit more elaborate ...

Re: Unlimited RAM/ROM

Thank you for the LLVM info! For the video, eh, sure, the SPI RAM kernel was made with the assumption that you would use the SD card lightly (given that there is SPI RAM), envisioning processing one sector in one frame at most typically (which should fit, so that case no flicker, and yes, running ov...

Re: Image viewer for SPI RAM

Thank you, it is part of the Square Kernel , so it is fairly complete for playing around with. The biggest shortcoming of that I think is that I never finished a differently architected sprite blitter (the wreck of which is still around, maybe one day), it is only internal stuff (so no interface cha...

Re: Unlimited RAM/ROM

Wow, this is super-cool! By the way what about the instruction set of the emulated CPU? Could you give me some pointers on where should I start if I wanted to make a Clang/LLVM backend? How complicated is that? I am really interested as I have an instruction set laying about since a while which I pu...

A bit of time off, but awesome stuff going on here

Sorry for the long absence, just having somewhat rough time. Anyway, just checked in and saw this really neat thing from rv6502: Unlimited RAM/ROM , the coolness factor of which for me is that it emulates a 32 bit CPU which even apparently has a C/C++ compiler already! That's something crazy for sur...

Re: Super Mario Land

Huh, sorry for not being around, I was preparing for a trip to Hungary, and now I am there, trying to sort out my relocation proper, visiting some friends and such. No much access to Uzebox stuff. There is also a "junk" demo in there alongside with the plane which just throws some things on the scre...

Re: Super Mario Land

I see the export as c header option in GIMP. How does this handle tile de-duplication though? No de-duplication, that's just a simple tool to get you a tileset into 2bpp format. You neet to add the converter code to a map creator (tile de-duplication doesn't make much sense without one). So, there ...

Re: Super Mario Land

Okay. So, I'll need to change all my tile data and maps to work with mode 52. I would want to modify my own toolset to do that. How do you create the actual tiles? Look into the generators folder, there is a very crude tool there. It demands Gimp, within Gimp there is an option to export an image a...

Re: Super Mario Land

Maybe we need some kind of list of compiler/linker options that are labeled such as "DON'T USE THIS! BAD IDEA!". Also, I should have understood better what they did before I started using them. I would say, probably a pinned thread, as the list might grow while discovering stuff. There is one certa...

Re: MicroDuo if ever (2 x ATmega1284 system)

Wow, quite some ideas there! How about a 9th color pin that forces the output to white? bst/bld could be used with that pin to add some kind of overlay for cheap, or quicker 1bpp output. I don't see too much point in doing that as I already have a 2.25 cycles / pixel 1bpp mode with arbitrary FG / BG...
