I recently bought a gamehunter pro cd version

to play my burned ps1 games

i bought these burn ps1's on south america im sure these cds are ntsc

they are a copy of the game captain tsubasa j: get into the dream

i also bought a ps1 sony scph-5501 ntsc___ u/c

the ps1 reads the gamehunter pro and when i put the game is says start with mod so i press start and the screen goes in a big white start but it doesn't play. This game worked in peru with the sellers ps1 system the difference was that the seller had a mod ps1 system with a chip inside. Can anybody tell me how to fix this problem?
