3x memory access then, because read+read+write. And extra 0 to 3 reads in this work.

I think not. There is not only Tetris, but also Snake, and two types of "shooters" - one removes blocks, the other creates. And many variations of these four basic games.

Sadly, the Brick Game model from which the ROM dump was taken doesn't contain a racing game, which was in the Brick Game that I had as a child.

Does it count as a screenshot? Game select screen: HI-SCORE 0 /--------------------\ | | | | NEXT | | | [][][] | | [] [] | | [] [] | | [] [] | | [] [] | SPEED 0 | [] [] | | [][][] …

I wanted to run Doom on one of them. So far I have LCD control for SC6531E (with 9306 LCD panel), USB control for SC6531E/SC6531DA and USB control for MT6260/MT6261 (using API from…

From the ones I got, I found MAUI in the name of the firmware, and on Wikipedia I found these notes: > MAUI, a feature-phone operating system used with MediaTek-based shanzhai devi…

I don't know if the Mediatek chips have overridable pins, but the Spreadtrum does. There are also different LCD panels that have slightly different interfaces for which you will ne…

I recently ordered and researched the cheapest feature phones (and some smartwatches), looks like half of that market is occupied by Unisoc with the SC6531(E/DA) chipset (from the …

Explanation: 1. There are no data members inside X, in this case the size of the structure is 1 byte. 2. main() does nothing. 3. *x = new X[100]() - this requests a new array of 10…

#include static struct X { void* operator new[](size_t) { return (char*)&1[""]; } void operator delete[](void*) { } X() : X((char*)this - "") { } X(char i) { printf(i%3?i%5?"%s%i\n…

I have suggested them to look at my version, but I think UPX not much hardcore for that. Because I'm guessing decompression speed is more important to UPX than the extra 2kb.

I looked at the latest version of UPX, they began to use LZMA, if this is considered an LZMA decoder: https://github.com/upx/upx/blob/devel/src/stub/src/arch/amd6... Then it takes …

The compression method in UPX is much simpler (therefore smaller and faster), but the last time I saw it was over 10 years ago, something may have changed. But LZMA should provide …

Still can't improve this stage of encoding, it requires a lot of operations. Maybe there is something trivial, but I don't see it.
