my problem genaral dreamcast issue

that all wont playable dreamcast system freezing when i attempt play
f355 , orginal game disk or backup also ripped gdi with sd adapter

system stopping respond and freezing hang problem not with gd rom dreamcast game type media cdi iso gdi or orginal game disk or dreamshell

i was wondering maybe problem causing with weak laser head

thats why i bought same game orginal disk weak laser disk cannot read
cd-r properly but this time nothing change finnally im tried sd adapter

no resulth may be sd adapter still working with gd rom together

maybe psu problem cannot handle properly voltage or mainboard (gpu maybe cpu or ram

but i can play over than 10 games including like quake 3 arena
if dreamcast can play like game quake 3 well why couldnt play other couple of piece of shit i still cannot figure out yet
