SNES Jr Modding Questions

Hello i am in process of modding a SNES Jr i just ordered i bought the SuperCIC+IGR+50/60hrtz Kits from Bad_84 and i for the life of me probably my search skillz cant find the pin needed to lift for the 1 chip on the Snes Jr also a diagram or pics explaining how to do this for a Jr just ones for the older SNES models <<<feels sad any help pics links where to go is much appreciated below is my intended mods for the Jr

Modd's
SNES Vertical Bar Fix <<< new fix discovered recently
Fuse Repacement
LED Mod
SuperCIC+IGR+50/60Hrtz Mod
Cart slot mod for PAL/JAP carts in my USA SNES Jr
RGB/S-Video Mod <<< with no Case modification

Optional Mod's although prolly not needed is a Full Cap replacement experience with Duo's and finding best Video cable to use plus maybe new power supply to help keep electrical noise down hence wanting to do the "Vertical Bar Fix"


Edit: i just found the pin 111 i think sorry for making a useless post

BUMP!!!

hello gys i finished most of my work on my SNES Jr i got but the board i made for my SuperCIC as per the diagram i followed is for the PL snes 1-chip i cant find info regarding my SNN-CPU-01 for where to solder the S-CPU pin 9 all else i can find on my mobo also my PPU chip model is S-CPUN A please help guys any info on that pin 9 would help below is the diagram i have used

 

also to note the last 2 pics are from a thread i found here not installed to my SNES Jr as thats a PAL SNES in the bottom picture

 

Its s-rgb chip, pin 9.its at the back near the AV port

 

edit: so the CN3 point on my board do i need to solder that to pin 9 of the S-RGB or solder it to wich point on the X1 Xtal or can i leave it alone and just solder to pin 9 on S-RGB to point CN1 on my board

edit2: also Bad_Ad84 the 3 pin LED i got from you wich is green/red/ground?

 

No... Cn3 goes to right pin of the Xtal like it says. Cn1 goes to lifted pin9 of the s-rgb.

Led is common cathode

 

ok got it thx u and that the right side of the xtal with the contol ports facing me? and is it sfe to pull the 5v from the regulator? or can i use the sme point on that pal snes i apologize for the mulitude of questions i jus cant find alot of infor on this model as opposed to the 2 chip ppu models and thank you alot for your help i really do appreciate it

Chris

 

when controller ports are facing you. yes, you can take it from the regulator

 

uhm.. i cant find which pin is +5 on the regulator my volt meter is acting up grrr... can i be pointed to which thank you again i got all wired up jus lacking pwer now

Chris

 

Can you see the vertical bar on your Jr? My understanding is that this problem was pretty much absent from the Jr.

 

actually no this Jr doesnt show it i tested it on a Sony Trinitron 27in and was in proccess of doing your vertical bar fix but since i didnt see it on several games i loaded i didnt install it also to not the 7805 wich is the +5v on it and installing the cap for the bar fix goes to the regulator to? i know the other cap goes to the encoder if my memory serves me

 

220 uf cap Positive leg to regulator output, negative leg to ground. 220 uf cap positive leg to Vcc of encoder, negative leg to ground.

Bar is not visible in all games. Let me know how it worked for you.

 

which pin on the 17805 is 5v can someone please help on this my volt meter is broken n i cant find a datasheet on this particular TO-220 packge

 

"Before doing any electronic works you should have a functionnal multimeter" -My opinion

 

i agree just need a tip on which leg is output 5v

edit: im doing pretty poor on google search these days i guess i got the output pin left pin with controler ports facing me ground is middle pin and AC voltage is right pin with cntroller ports facing me

 

you could find out in 30 sec with ohmmeter

 

pin 111 popped off after a lil while of playing the system wondering if anyone wants the board i made selling it PM me if interested

 

what do you mean pin 111 popped off?

 

the ic leg is off of the S_CPUN A least i had a sleepless night and SuperCIC'd two SHVC-CPU-01's n i know i got to do the vert bar fix i dont trust these models also figure RGB and S-Vid out for the BA6592F

You mean you broke a leg off the CPU while trying to solder on it? D:
