AFTER 4 YEARS FINALLY SOLVED THE PROBLEM
i was thinking about it and how i had to leave my dreamcast turned on for so long to make it read discs, then when i opened it i noticed that it had a lot of capacitors on the power supply
then i thought "what if its a faulty capacitor that's not giving the exact current?
i rushed to google to search about this and i found this videohttps://www.youtube.com/watch?v=ilhfndjs6ew
so since changing capacitors would be really cheap i decided to give it a try
AND IT WORKED
now everygame runs everytime 100%
here's the list of capacitors changed on the power supplyDreamcast Power Supply Capacitor List:
