Can't wait to see what game you make on the GBC. Its a personal favorite of mine to code on as well. And with how awesome GB studio is its now more accessible than ever to work with. And in case you're wondering my GBC game is called Eternal Memory.

@@Bobbias I don't think its that bad honestly plus it's actually really competent at making more complex games. I've managed to create a pseudo real time reflection using just the stock visual scripting.
That sounds a bit like multiplexing which gives more capability to a limited resource by working on one bank or area of the screen at one time, which happens so fast that the person playing the game can't see this.

a great programmers code is like a master close up magicians act: nothing flashy under the surface, super efficient and seamless. The average programmers code is like a magician you hired last minute for your kids birthday party: it kind of works sometimes but is otherwise a total mess of copied tricks and a pigeon in a hat, and the pigeon is dead and useless but they kept it in the act anyway.
This is amazing... As some how now works closely with cpu hardware and firmware learning about the limitation that we went through is fascinating... And i see how some of the stuff/limitations from 90 is till there in mordern cpu... We just find more ways to go around them
Each 8x8px tile of the background nametables can use a distinct palette index. They are indeed grouped in chunks of 4 tiles internally because each index is encoded on 2 bits, and the whole chunk is represented by 8 bits (1 byte), but the index of each tile of the chunk can be set individually. ;)
The good thing about the GBC is that you can actually use cool things, like C instead of Assembly. I did the iconic DVD bouncing logo and made it run into original hardware (GBC and GBA)
fun fact: on reset it only clears certain parts of ram, this was exploited to make some games able to set ram values which are then used by other games to get extra lives or levels or such, famous example is using tennis to break super mario bros
If you were using C, it'd be awesome to have a C23 compliant compiler to handle resource embedding. Towards that end, the oscar64 project intrigues me. It's intended for the C64, but it shouldn't be too difficult to modify it for other 6502 based systems.
@@rusi6219 For a lot of the things I see getting added to C and C++ both these past few revisions, yeah. I hate constexpr and consteval and they're adding constexpr to C.
Now I'm really interested in the difference between NES and GBC. Especially black cartridge games look quite similar to NES games, apart from the resolution.
Question: is it possible to alter the color pallete of a sprite on a per-LINE basis rather than a per-cell basis if coded correctly? Sorta like how the Atari 2600 did to give the illusion of extra colors for a single sprite?
You'd be surprised by how much you can do if you have a couple of kilobytes of storage space, if you just didn't have any of the bloat of modern software
I've doing it all in assembly for now, but I might use some music tools later since making music for these machines is like writing a whole program on its own
What a great idea for a homebrew NES game! It would have been cool if a game like this had been built into the NES so we could have played something even without a cartridge inserted. I wonder how feasible it would be for someone to hack that feature into an NES...
A few swag genesis games utilize alternating color palettes as a way to save space as frames of a sprite are stored in individual colors of the sprites, with the limitations of the nes having it so sprites can only alternate 3 colors, this can allow only 2-3 sprites created by alternate color palettes but nonetheless could this be utilized so background sprites can be “animated” if you can change the colors of the palettes?
Super mario bros was made in assembly and most of the prg rom isnt full because compiled assembly code isnt that big and they moved the compiled assembly to the rom and they made sure it didnt go to the blank prg area so that is how super mario bros was made in 40k (a lot of the rom is 0s) Thank you for reading.
would you be willing to do a video with an in depth explanation of mappers? I've been digging around on nes games that are over 40kb, but I'm having trouble grasping the concept
I've mentioned mappers in this video here: ruclips.net/video/Lf1jer8y6Pc/видео.html Basically a mapper facilitates bank switching, where a section of memory can be switched out for another portion of memory from the cartridge.

Only in the USA. The rest of the world was fine. In fact, the UK had a home computer/bedroom coder boom from 1982-1990 where games made millions.
