Re: Need help to get my NES clone to work properly

I checked all tracks and components on the board (also investigated A4 and A8 connection of the NOAC), all are fine, I think the NOAC is fried up whyever because there is nothing broken, I also changed the components with exception to the clock (the thing labeled with 26.6017mhz) I give up, I will d...

Re: Need help to get my NES clone to work properly

I had no luck with a power adapter. I also removed the internal game to look if there was any issue with it, but no luck, the graphics look the same. I tested all traces I could and it seemed like there were no bad connections or shorts. Are there any other suggestions?
Also a pic of the NOAC Board:

Re: Need help to get my NES clone to work properly

I used new batteries to see if the voltage was too low, but no luck. All carts, also the built in, have the problem with graphics. I will try to get a suitable adapter, but as I said before, it worked with the battery without issues for some time.

Need help to get my NES clone to work properly

I bought an NES clone from the bazar for 3€ on a pile of rubbish :D I went home and opened it to see if there are any shorts or defects on it, but it did not seem like it. As I do not own a proper adapter to power the clone I connected a battery to power it (the clone needs 9V to work) For some time...

Re: Help needed: Rockman 6-in-1 multicart hardware

recently i got my 27c322 chip and wanted to start to build my own cart, but then i noticed that my latch and switch are 74ls4053 and 74ls174. i did some research if the fact that both chips are from the ls family would work out with the project. i read that the reaction time of ls chips are lower th...

Re: Help needed: Rockman 6-in-1 multicart hardware

So instead of /oe, i should connect the /ce pins of the chips to the 74hc139 and use the /ce connection on the pcb?

Re: Help needed: Rockman 6-in-1 multicart hardware

i read somwhere that it should be possible to connect 2 8mbit chip as 16mbit chip for this.
can i take a 74hc139, connect it to /oe on pcb and connect the 2 /oe pins of the chips to the 74hc139, or is it done in another way?
thanks in advance:)
