The TSOP variant is much better - cheaper and less time-intensive



How is it going on your end Rx_79?

[Skuttzor]

I use the TSOP method as well, it's super easy, i just use a dremel to remove the chip (w/o damaging the board) and then heat the pins up that are left in and push em out, then i all gotta do is solder the TSOP into place, screw it back together and play

In this version do you just program the flash chip and then solder it on the TSOP adapter and the two of them on the board? Or did I understand sth wrong? Read a bit about this stuff recently.

Also could I use this programmer:

Yes. You solder the programmed flash chip onto the adapter and this package then onto  the PCB without any extra wiring, because the pins of the TSOP get aligned correctly to the mask rom pins.

Don't know about the programmer, sorry!

Hmmm.... The soldering job of the flash chip looks pretty difficult isn't it? SMD soldering on such small solder points. Yuck.... I'm just an amateur when it comes to SMD soldering so the smaller the more difficult for me.

[destructiveme]

Its pretty easy actually.

I never did soldering before trying the standard SoM2 mod, and I never ever tried SMD soldering before last friday and it worked on the first try!

Just be sure to the "foots" touch the correct pads and not to create any bridges!

I learned it with this video: http://www.youtube.com/watch?v=vZ1qisX52rI

That does look alot easier.

Where do you get the tsop adapter and what chips do you use?

Is there a guide for this method?



 

[Rx_79]

Oh , and I forgot 2 mention

I never got one to work, six failed attempts.

I dont know what I am doing wrong.

On the mad 1 chip when connecting the moe line, do i have to disconnect the mad 1 from the board at that spot.

If so do i have to do that for the rco connection too?

I dont think I can stomach this four eprom method any more.  What parts do i need for the tsop way?  I would like to take a stab at it.

[destructiveme]

If you want you can send me one or two failed attempts and I will tell you what went wrong!

You don't lift the pins when connecting moe or rco.

I guess you still solder wrong or destroy pads, I wouldn't recommend you the TSOP way yet, these are waaay tinier

[Rx_79]

Okay send me a private message with your info, and I will drop it in the mail

[destructiveme]

Hi, did you send it?

[Rx_79]

Sending it today, sorry with all of the holiday stuff going on I havent had time to get it boxed up.

I have some questions on the TSOP method

1) What is it, is it flash? and like eproms, do you have to fill up the chip?

2) Where do you get the adapter to solder the chip to the SNES board?

3) Do the TSOP chips cost less than using multiple eproms, and where do you get them?

4) is it for the win?

[Rx_79]

when using this method, do I solder down the 29F032 chip, then program it through the tsop adaptor.

[scarmullet]

where are you guys getting the AM29F032 chips? I have searched places that say they are not manufactured anymore.
