I tried several ones and none worked for me. Maybe I did something wrong. I'll upload a video of what I got. But it is basically corrupted images and sound with a band (pm?) moving slowly from top to bottom.


list of things that could be causing problems

- using pal encoded videos on ntsc machines and vice versa
- files (avf) not contiguous (defragmented) on the sd card (use contig.exe on windows/filefrag on linux to check)
- there could be sd cards that don't work well for this purpose - TBD
- i might have broken some timings in player for ntsc (i can't test that) - TBD, i think rdea6 said ntsc videos worked for him, need more confirmations

also there could be a bug that is not obvious but could lead to video/audio quality issues, a/b testing with side2 would be needed but i don't own one so i can't tell whether it's working as it's supposed to (i especially didn't like that high pitched noise in philsan's video but can't tell if it's the same with side2)

Yes, there's a similar noise with SIDE2 too.

Hear near the end.

 

In the other thread Phaeron just explained:

 

It is the 15KHz carrier from the PWM technique used to generate the audio. Standard 4-bit volume encoding can be used instead, but the sound would be muffled at the high end instead.

PDM would have better quality, but there are currently not enough cycles in horizontal blank. Volume-only is LDA + STA, PWM is LDA + STA x 2, PDM requires LDA x 2 + STA x 2.

Hi everyone,

Would this configuration of stick controls with the TAB rotation drive slots joystick assignable be more intuitive? or?

 

stick up/down  move up/down  one entry on the list

 

stick held up/down then button  move a page of the list at a time up/down

 

stick right/forward  go in a directory

 

stick left/back go out/back a directory

 

button selects the image

 

stick right/forward and button assigns a rotate slot like tab does for atr's.
