    Provide more info maybe???

    1) Do your original discs load?

    2) What is the condition of the CD laser? These are 15+ year old systems now and lasers will need replacing and always use high quality recordable media.

    3) The installation looks a bit messy with the wires, could be a lot more tidy.

    1) originals load.

    2) laser reads from first run, its cleaned, it reads audio and originals, and burned discs reads but only to playstation logo part. I have few burnet discs, all of them reads to ps logo and it stops there but some have letters scrambled and some copies displey normal logo.

    As for 3, do you need better shot to where wires are soldered?
    I didnt do the mod, if i did it would look perfect. i bought it on a flee market for 2€, only thing that was wrong was capacitor on power pcb that i changed...except that all looks fine...except i cant get my copies to load.....maybe my copies are bad idk???

    If i remember correctly there is no big secret to it, but i would use imgburn to do it.

    But if the same burned CD runs on a emulator then we are climbing the wrong tree.. but give it a try..

    I managed to get it work when i burned it using Alcohol 120% -->RAW DAO --> Enable Buffer --> Play Station Datatype and it burned at 42X the speed by accident, i did not saw, and it reads just fine....

    Sorry for bothering you all, but it seems that Discs burned with ImgBurn did not work for me, only Alcohol 120% burning software i guess...
    I never had PSX so im new to this all, but i remember Alcohol was popular back in the cd burning days, so i decided to go old style method. At first i thought i have no mod chip cause i used imgBurn as sugested across internet, but that did not worked for me i guess.

    Thanks anyway to all!

    What speed are you burning them at, I've had issues with Dreamcast and my PSX reading them above 4x speed.

    From the installation diagram it looks like it's a Multimode 2.x.

    I've had more luck when burning at 24x than 4x, so "burn at low speed" is probably just a myth.

    It was true when a modded PS1 (and maybe you had an early model with the self-melting optical drives) was the coolest thing to have and Cd burners were racing to the highest reasonably advertisable speed, nowadays it's much more likely that your optical drive and discs are actually optimized more for their highest speed instead of the slow ones!

    Back then it wouldn't be an issue either since most burners did 8x maximum :P

    Well my Dreamcast is made in Japan, its rev1...idk if that has anything to do with it... Anyway, as for DC burns, i burn them in ImgBurn with some kint of Imgburn patch so it can see cdi/gdi images and @ 15X speed. I would burn slower but my cd burner can only do 16X minimum, where my old one (Pionit) could do it @ 1X minimum!!! (im so sad it broke, it was so good, i abused it to the max).

    Anyway, PlayStation burns are 16X also (min for me...although i wonder if i can override that limitation or is it physical thing) but i burned first one today by acident as 42X and it works like a charm, no problems what so ever!
    All images i did with ImgBurn fail to load. Maybe its ISO, idk, but i dont think so...

    Multimode 2.x. so what does that exactly mean for me? Are there any differences in PSX chips...i mean practical differences?
