Damn this is a great tool ! well done !

Be careful, you're not using accurate Genesis palette.

Genesis palette contain the brightness levels for blue, green and red respectively. Possible values are 0, 2, 4, 6, 8, $A, $C and $E.

3-bit value
Brightness (0-255)
000
0 ($00)
001
52 ($34)
010
87 ($57)
011
116 ($74)
100
144 ($90)
101
172 ($AC)
110
206 ($CE)
111
255 ($FF)

Also, if you could have a function that count the number of different tiles after qualetization, it would be greater than great !

Very well done and thank you for sharing.

Thank you very much for the extremely detailed explanation.
You’re absolutely right — with the current specifications, the brightness levels aren’t the official ones, but simply the result of dividing 255 by 7:
0, 36, 73, 109, 146, 182, 219, 255.
Since the core library this app uses isn’t one I created myself, making changes may be difficult, but I’ll think about possible approaches.

As for counting the number of unique tiles in the image after Qualetize, I think that feature should be relatively easy to implement.

I really appreciate your feedback — it’s incredibly helpful and motivating.
Thank you again for taking the time to point this out.

In 0.4.0 I’ve:
- Switched the Genesis preset to the accurate non-linear palette levels (custom per-channel quantization).
- Added a unique tile counter (flip/transparent aware).
