Re: For what for EPM3128ATC100 on Chinese SNES repro?

Maybe the PCB is universal for LOROM / HIROM games and this chip is responsible for that (it switches LOROM / HIROM games automatically)

Re: Graphic design of NES games

Vice Project Doom (Gun-Dec) has a very interesting looking tropical forest.
For me, it is one of the most beautifully designed games.

Captain Janush The Galaxy Hero (shoot 'em up)

Two games from 2018/2019 - my first attempts to make a shooter game. Nothing special, simple mechanics, we just shoot other space ships. (NESASM3).

Kapitan Sowa na tropie (Captain "Owl" on the trail)

A game inspired by one of my favorite childhood games - Montezuma's Revenge. The Screens / Levels are not yet designed, this is an early version of the game engine (NESASM3).

Re: Following one object (sprite) after another (Tracking)

Works great, thanks :) My earlier code has changed a bit, unfortunately it is larger, but more accurate when it comes to changing the speed of the object. I have to optimize it all to make it as small as possible. Follow5.nes: lda Timer_Counter inc Timer_Counter eor #$ff and Timer_Counter sta Timer ...

It works of course. I am interested in how it can be done better, simpler, faster etc. I did it as best I can. Thanks. It works great.

Following one object (sprite) after another (Tracking)

I have a problem with the object 'vibrating' when two are on one Y / X line (caused by the change of opposite directions of movement per frame). Sometimes I use a delay that slightly masks the problem. I don't know any other ways, so I would love to improve it somehow (in many commercial games I als...

Re: Alien Isolation

The game has not finished so there are not many things. It's all game concepts, whether they will be completed I do not know, it all depends on time and desire (I do not do it for money, everything hobby). The Jet Set Willy engine is almost ready, all I have to do is design the levels (not 100% iden...

Re: Alien Isolation

I don't know much about compression, that's why I always used the whole nametable :) I have to read about it sometime. Unfortunately, my programming skills are quite poor when it comes to optimizing the size of the code (and not only;)) I think I found an exploit with the boxes. Going to the screen ...
