Comparing with this : http://up.iranblog.com/images/5m4y6ylg3q38zy71ly.png It is in the right direction, I think. If we could I know there is an NES mapper that works the same way. We could look up the PCB on Bootgod's database and have a look-see. Reset based multigame cartridges doesn't need any k...

Went fine on AM29F040 with 4 MMC3 TLROM games : http://www.upload-jpg.com/images.php/8e2e81952/DSC00457s.JPG http://www.upload-jpg.com/images.php/be7181951/DSC00462s.JPG http://www.upload-jpg.com/images.php/e5c891919/01.PNG http://www.upload-jpg.com/images.php/216761915/SIGNAL.PNG But there is a pro...

I *highly* suggest you invest in a multimeter, instead I want to listen your advice. :) Do you think this multimeter can meet my needs : MULTIMETER (PDIP ATMega8 version) http://up.iranblog.com/images/5vhimam345mb4mpvuwe.jpg If you know any better one, please let me know. If you use the circuit I p...

I am sure 9050 is a clone of MMC1. I want to buy 9050 and use it, but first I have to find out its full part number. this chip may be numbered:ks5361 Is this just a good guess or you do know of it?! Do you have any datasheet or pinout for this chip? However I can find out the pinout by using the ca...

You can make a reset signal by using M2 (phi2) to charge a capacitor. Then discharge the capacitor through a resistor. I don't know what values to select for the parts, or if there's more to it, I haven't thought it through completely. You'd want it to charge and discharge fairly fast, but not so f...

Wow, Kevtris is here! :shock: I am not so much smart to dump this cartridge without desoldering the chips, on the other hand it is no use of schematic without owning the code for selection screen which is inside 27C256. Anyway thanks for your advice man! :) By the way this cartridge is not my ace ca...

I still have another so called crap! But maybe this is my ace card!! :D When I found this cartridge I was just looking for its AX5202P and I was so much hasty that I screwed up the board a little when I was desoldering the AX5202P from the board! http://krauser.persiangig.com/image/Multi/Front1s.JPG...

I can remember once I had a cartridge which worked like this, games changed with pushing reset button!

This is really great! That site has a lot of good information. Thanks. Since I am using Famicom, It seems that I can't use this method : But why was this reset-button method rarely (if ever) used in production NES or Famicom multicarts? The easiest explanation is that the reset signal we're using fr...

What about other chips? there are 3 TTL chips (74HC161, 74HC153, 74HC138). How should I use them? Unfortunately the picture is not clear enough to find out its schematic.

I just want to produce a multigame cartridge by using AX5202P. Can someone help me? Or at least provide me a shot from a multigame PCB which uses AX5202P.

I'm confused why you would want to reproduce a $3 famicom cart that is still avalible in abundance? Can you provide me a shot from its PCB? I have a Master Fighter II (Mapper 189) : http://up.iranblog.com/images/i42nttsbznh2o4g5jk.png http://up.iranblog.com/images/kaz7ab45d601362vhyk.png http://up....

Hi I am back with another n00b question :D I want to reproduce a 3-in-1 cartridge which is mapper 205 : http://up.iranblog.com/images/tsv87gkldyxkztn94liz.png http://up.iranblog.com/images/jnasmwv6c0df9x72h3nl.png Does anyone have any schematic for it? Is it possible to find out schematic from mappe...

I can take a picture of the marking on the chips for comparison later, if you want Ok, I can take a picture too Not sure how I would get the pinout for it though UM6561 NOAC pinout Well this all confirms my suspicions that FARAD is working on an Iranian Famiclone I am working on everything about Fa...

Please tell me your idea about these prices :
