now it's a more fun trouble shoot than to look into the cart itself hehe

Sorry i did that in a rush + i didn't check the settings

ill know next time..




Still trying to figure my problem out.
resoldered some of the legs i thought were not that great....


I tempt to say it's maybe that wire that is not good.
but still i would get something on the screen or?.

how i solder is turn the board upside down & solder the ''round'' with the pin coming out I put not much solder but at least it stays on it... But i am not that brute.. with the pcb... & also near where the socket legs are coming out the ''top part doesn't have any trace at all the bottom is...

Just to be sure I took this new ''excite bike cart & did the same thing but this time i didn't miss pin 5 in the back'' Same thing occurs............................. Dammit... I put a miltimeter on Dc? I was reading on every contact. even the wire i installed i guess it's good news.... as i don...

I had a spare Excite bike opened it up Kept the 2 Original chips tryed it in the Nes didn't work... stays on a Grey screen I know how to make work a nes in 1 shot normally all my games work in 1 try.... then i retryed puttin the Excitebike chips onto it's board i just pulled them from without solder...

i don'T have the ''eproms anymore or rom'' but i did try ie hockey same story.... I check the board the wire seems okay maybe it touches the circle but it doesn't go all the way trought .. (it's impossible to make it stand up.. or i would have broken the socket pin... & on the PCB everything see...

yes it says it's ''ok...'' i checked the cart I even Redid the socket with the Wire.... to be sure cause there was a bit of solder to 2 points that was touching so (it was making a bridge) still doesn't work......... i have 2 other eprom i could try they are blank... i will try them with excitebike ...

Ahh I forgot to mention my error it's ''The excitebike cart i am trying to burn'' 28 pin dip (both chips) Nrom board 128 I am using EPROM35 program I choosed Eprom 27c256 in the menu I hit load (chr ) or (prg) then hit program chip then it goes to 100% & verifys... this is what i did The Schema ...

I burned it Manually 4 times for the chr & 2 times for the prg

Tryed it it doesn't work... hmmm

weird...

Got my eprom burner today



Just tryed burning Mario bros (cloud hack)

Burned the Chr once & i burned the ''prg'' twice because it didn't tell me it was full ....

should i burn it until they say me ?

Let me know

thanks!!:)

About AT29C040 I have asked him to trade the at29c512 vs AT29C040 I will have to see if my friend have it in stock if not i will get refund & buy from futurlec I bought Eprom Uv erasable because the 28 pin flash is no where to be found like imposible to find I bought a UV eraser that is on it's ...

ahhh damn i didn't know for the chips i really tought it would gonna be ok very confusing to put 512 at the end i always think 512K ah well.. I will try to ship them back to the person i bought them too.. but the 27c256 are they okay for my excite bike cart? because if i made a silly error there too...
