Personally I don't like that much too small. I never keep anything in my pockets, even my (dumb) phones are just thrown in my bag when I go to places, it feels inconvenient and makes me worry that stuff falls off or maybe gets stolen. I usually only have a wallet and a folded up bag in my pocket whe...

Thanks! Real hardware (TM) also arrived meanwhile, Alec generously sent me three 256Mb SD cards of various brands (if I duct-tape two together and ram it in the socket, will I be able to run Tempest? :lol: ), so I have some foundation for testing what I do. Just the right time, actually, just when I...

It arrived today! Looks great, thanks Alec(Uze)! :) However right now I have a silly problem... Yes, I still damn have a silly problem... How I could get back to the bootloader after trying out a game? I loaded D3thAdd3r's Adventures of Lolo demo out of interest as my first try, and now I am kind of...

I think I am starting to understand the portion which interests me (sector loading, since for whatever else: initialization, dealing with the FAT, your small SD library should fit well). However I found some points which feel blurry, and would like to know if I understand them right or for what purp...

Sprite recoloring is also done. Mode 74 code is up on GitHub, attached an example demonstrating it. Now it became quite cluttered... The recoloring function works by using a set of 256 byte tables, each table containing data for one byte (pixel pair) remapping table. It can be enabled by specifying ...

I did a bit of search, and found this on DigiKey (I hope the URL contains the search query all right). That is, there seem to be landscape LCD modules at 320x240 at acceptable prices. They are described to take NTSC signal, but that doesn't mean composite, just the appropriate clock. The cheapest on...

I like that boxy case design, looks good both in white and black! I wouldn't like that much a flip-up, it is a potential point of failure. Have a decent robust brick which in need you can hurl at somebody, and the thing would still work fine afterward :) Scrolling through the topic I see there are c...

I figured out how to get rid of that egregious flicker in a simple manner. Attached demo uses it, for a good measure I threw in even more pixels (100 this time). Actually the culprit is the WaitVsync() function of the kernel which is good for simple uses, but completely hinders proper frame manageme...

I am interested to see your code Then here is the beast in all its glory: https://github.com/Jubatian/uzebox/blob/mode74/kernel/videoMode74/videoMode74_sprite.s The importance calculation for sprites starts at line 665. Further details are in the RAM tile allocator below: adding up importances at l...

I completed the pixel put support. Yes, it is not fast, but putting some 10 pixels is faster than putting a sprite at a non-aligned location, so it is quite useful for particles and bullets to gain both cycles and RAM tiles. I attached a demo, just the previous one with X + Y flipped character sprit...
