Repair General

>save file occasionally deletes itself

Typically when the battery is dying it usually doesn't stop all of a sudden. Sometimes they will still kindof work but not consistently. Sometimes when you boot it up only one save is gone. Replacing the battery should fix this. Also keep in mind that I have had carts that would wipe saves if they don't boot properly so make sure everything is very clean and will load before you try booting it.

>>3929967
okay, the cartridge is actually second hand, so I'm hoping there is no irreparable problem with it. Maybe it needs a clean

>>3929963
I have a DKC2 cartridge with a few problems;
>label sticker is faded
>Looks like I can buy a replacement sticker from retrogamecases, or is there a better alternative?

That's really up to you. Each vendor has their own way of printing labels. Be sure you find out what resolution they print at or find out before hand.

>save file occasionally deletes itself
>I assume this is battery related? Perhaps a simple battery swap will fix this?

It might be the battery or the S-ram finally dying. A battery is the right place to start. I know though that DKC2 is VERY finicky when it gets dirty and some times can trigger a copy protection screen that wipes the saved games.

>cartridge is yellowing
>Is it easy to just by a replacement surrogate cartridge case? Where from? I hear retrobrite makes the plastic brittle or something

Again it's up to you what you want to do. Retrobrite might take a few treatments but if you're getting a new label, it might just be better to get a new case as well and save the labor.

I have a Mega Drive that I'm looking to breath some new life into, if I install a region switch, will that allow it to play games at 60hz, or simply change the region it registers as?
Essentially, will it be able to turn it into a Genesis, or some weird hybrid Mega Drive that plays Genesis slowly?

"Region" on MD/Genesis is achieved by a combination of language and frequency settings.

You need to modify both parameters to achieve 100% game compatibility.

EXP should read ENG on that image, just in case you were sat there scratching your head.

>>3930832
But what if I have Model 1 that is supposedly region free?
Only 50/60Hz switch?

Has anyone tried out this circuit to get YPbPr from an RGB console? Trying to get my Dreamcast to look good on a consumer grade CRT.
If it works well I'm gonna do a second one for my n64.

>>3930836
also PAL console

This is the most simple region mod you can do with one single switch thank to the fact that the console always defaults to English and 60Hz when no connection is made.
Paired with an RGB LED it's pretty awesome.

>>3930836
That's not it, the early Model 1's don't have TMSS, which was an effort to lock out unlicensed games.
You will still need to switch the language, but there is a method to get all 3 valid regions on one 3-way switch.

>>3930861
That's exactly what this >>3930854 is only that you don't unnecessarily have to read a whole bunch of shit.

>>3930836
Do you mean an asian PAL-I one? You still need to mod it the same way.

The only thing "region free" about it is the cartridge slot.

Guys what happened to the retro computing general?
I have questions regarding older PC Im trying to maintain.

>>3930906
>>3930861
Thanks guys. It's EU PAL I think. I live in central/easter europe so who knows

>>3930185
>S-ram
OP here, I am unfamiliar with this S-RAM issue. Are you saying if/when s-ram dies then the cartridge is irreparable?

>>3931757
It's the chip that holds the actual save data. It wouldn't be irreparable if it died. You'd have to salvage an S-ram chip off another game with the same value.

according to https://snescentral.com/pcbboards.php?chip=SHVC-1J1M-20

It uses a LH5116D-10p. Finding one (or an equivalent) might be hard in this day and age though, at least a new one would be hard.

But like I said. it's most likely the battery. If you have a multi meter you can test the battery and see how many volts it's putting out. Anything below 2.4~ ish volts and its getting into danger territory

The buttons on my old NES controllers have started to stop responding. Is it a problem with the rubber thing that comes in contact with the curcuitboard or is it a problem with the contacts themselves?

Welp. I was trying to mod my console today. During testing it shut itself and it's not working.
No power. So console or power supply problem.
anyway RIP
I'm not even mad

>>3933052
Could be either. Open it and check.

>>3933127
You didn't happen to short the pads between JP1 and JP2 or JP3 and JP4 together did you?
Get out a multimeter and check the fuses and see if the voltage regulators put out what they're supposed to.

>>3933756
Thanks for support.
It's probably power brick since it does not power other compatible devices in my home anymore. Just ordered new. I did not seen any fuses on my MD. Gonna check those two voltage regulators but for the love of god I can't find my multimeter anywhere.
Anyway shits gonna wait for one or two weeks. I've got a lot of my own work and I need new soldering wick anyway.

>>3934214
Oh yeah it was VA4 board with that capacitor on jumpers
Power brick is 10V 1.2A

>>3934214
>>3934224
Huh, yeah I forgot that the sega cd is actually the only thing that has a fuse.
Guess your mega drive is probably fine anyways then if the brick is just dead but checking the voltage regulators won't hurt.

>md_jumper_settings.png
Just sad

>>3930838
No. But I've used a similar but well designed one. Works great. I'd go with VGA for a DC though.

>>3935171
I don't get it.

Why sad?

>>3935236
It's a shitty picture with misspellings depicting information that's widely available in many places in a more accurate and informative form.

>>3930832
If I set those jumpers to skull position will the Genesis die?

How to get a sticker off the label of an expensive cartridge?

>>3929963
>Is it easy to just by a replacement surrogate cartridge case?
For some reason, no. All there seems to be on the market for any console in terms of replacement cartridges seems to be cheap crap that's obviously fake.


I've often wondered why this is. If you're going to pay all that money for the tooling, why not just make a 1:1 copy

>>3938016
just delete the whole problem with a sharpie

>>3938014
You would effectively short 5V to ground so yes

Can anyone explain this mod to me?

Never seen HDMI on a PlayStation before.

>>3939321
Someone removed one of these cheap ebay upscaler units from ebay from it's case and crammed it into a PS1 case.
End of story. Don't be a retard. Don't do this.

>>3939359
That's what I figured.

They want £100 for this lol.

>>3939363
If you ask me all they should get for this kind of shit is a bullet to the head.
This is console gore material.

Not really a repair thing but i am thinking about importing a NTSC-J Controller and wanted to know if it'll work on any regular American SNES.

>>3939396
Yes, though I don't get why you'd really need one.

>>3939423
I found a cheap one on Ebay, all of my regular controllers have worn circuits and i don't think i can fix that.

>>3939425
I meant why not just get a SNES controller considering it shouldn't cost you much more and you wouldn't have to get it all the way from japan making shipping take much longer.

>>3939438
Sick ass coloured buttons and the SFC logo though

>>3938016
Whoever decided to slap stickers on cartridge labels should be shot.

Step aside plebe

>>3929972
I've had games do this too, all SNES ones, Earthbound deletes my shit if it doesn't boot correctly, as in it boots to a glitched screen. A good cleaning will fix this, though. For DKC it's not that big a problem, for RPGs it is, so whenever I play an RPG I don't take the cart out til I beat it.

>>3939595
i actually really like this

>>3938016
That type of sticker seems like the type that the glue will dry up after a few years unless its a rental sticker.

Peel the edge slighty to see if the glue is still sticky

>>3940225
I tried a few years ago and it didn't seem like it wanted to come off with a safe amount of force. Wasn't going to try harder and risk tearing the label.

>>3940297
could always try the hair dryer method to take it off

>>3940182
Yep i actually got it for my ntsc j super famicom
Dont get the official sfc controls because the cords are like 3 feet
Fuck that noise

>>3939595
Every single one of these I've come across has been cracked and/or rusted. Would be cool because those shoulder buttons seem excellent.

>>3940314
Even the shoulder buttons have turbo, i only got it because i figured a REAL one would run me 20$ or so since i was at a gaming store where shit cost money
6$
