Mainly, I'm fan of "retro-programming".
6/7 month ago i started to programm on PSX. During 1 month i read the various low-level documentations found on net, done my own MIPS compilator and pseudo-linker to create psx executable, take my modchiped PSX(7500 PAL), and start to test it.
After a long stop period (due to a lack of time) i went back to play with my Psx (Currently my knowledge is very limited: deal with GPU, little with SPU, DMA transfer and some bios functions).
And recently, I discovered this forum.
However i don't use SDK (no satisfactions to make programs thanks to libs without understanding the details of Psx working) there is some fine infos that i discovered in "Sony Dev CD": thank you for posted it:)
So I'm here ready to ask/discuss about low-level programming details on PSX.
