I recently added a ps2 to my xbox powered arcade cab. I fired up tekken 5 and was ready to play some arcade tekken 5 at home...

but i forgot to plug in the controler cables to the ps2...tekken 5 loaded up with no controlers attached to the ps2 and to my amazement my tekken 5 home console game was asking me to insert quarters!!!!!!!!It is the exact same game as the system 248 arcade hardware! All i need to do is figure out what input adds coins and i have a real tekken 5 pcb here (saved 450.00 at least)!

so to emulate system 248 at home get tekken 5 and ps2...load the game and remove controlers.

I cant believe no one saw this yet

I believe Tekken 2 did this as well on the psx

...actually, all the other tekkens

just try not to have any controllers plugged in and bam, it says "insert coin"

I think it's more of a novelty though

Namco is known to be shoddy is this regard, since they often start building the console ports directly on top of the arcade one. A slight mishap.

it looks sweet on the cab...there must be a hack to let you play like arcade mode if all the code is there...

I think agozer meant more along the lines of modified arcade code

Correct.
