Support / Re: N64 plugin permanently sold out?

Thank you so much! How strange, I remember looking just a while ago and it was out of stock. Can't wait to try this out!

At the time of writing there are 71 available at the DragonBox Shop:

https://www.dragonbox.de/en/134-retrode2-n64-plugin-cart-reader.html

I thought they stopped producing these with integrated controller connectors, can anyone confirm they're once again being produced with the controller ports?

Support / N64 plugin permanently sold out?
« Last post by Nori on 09/Mar/2019 10:51:36 PM »
Does anyone know of any place one can still buy an N64 plugin? Now that save backup is possible I would love to get one, but it seems to be sold out and has been for the longest time now.

General Discussion / PlugIn Master Cover Art
« Last post by bumfacekilla on 09/Mar/2019 12:59:45 PM »
Hi All,

I'm new here so please delete if inappropriate, but I have created a cover sleeve for the Retrode 'PlugIn Master' that should be properly formatted to fit into a Mega Drive / Genesis game case. Feel free to use it if you like, I cannot claim ownership of any of the assets used. :D

Hello, can I purchase one of these plugin PCBs? I can also provide my own HuCard slot.

Support / Retrode 2 corrupting SNES sram?
« Last post by Driftwood on 05/Mar/2019 04:16:10 AM »
I just received my retrode 2, and the first thing I tried was to back up my saved games from my US Secret of Mana cart. Unfortunately, the srm file produced by the retrode doesn't work on my sd2snes, in Higan, or in SNES9X, and when I tried my cart in my Super Nt, I can no longer access my existing saves.

I read a similar post of someone having a problem when trying to dump their gameboy saves, and the problem ended up being a manufacturing problem where one of the pins was bent, but I don't see any obvious issue with the pins in my unit (see attachment -- sorry about the low quality but the board has a 128k limit on uploads). I also saw issues with snes saves when the unit was set to 3.3V, but I double-checked that I have it set to 5V, but no luck.

I've attached the srm from the retrode2 if anyone can help me figure out how to rescue my saves, but it would be nice to know why this happened or if there is a fix.

Thanks in advance.

Support / Consistent unpredictably bad dumps of a single Game Boy Color game
« Last post by obskyr on 03/Mar/2019 06:43:59 AM »
The game in question is Kotobattle for the Game Boy Color. The symptoms are bizarre: no matter how many times I dump it, between 60 and 110 half-random bytes are incorrect. The contacts are immaculate and shiny (I even gave 'em a peace-of-mind clean with the ol' IPA and cotton bud combo). I dumped it ten times, and the results are these:

Code: [Select]
$ md5sum Kotobattle-*.gb
d58feb9bbe47a85dfbbdd541d278527b  Kotobattle-01.gb
47ca90c3e3f4f0f2d90eb7892fb5c4b2  Kotobattle-02.gb
5cc853c53f5e059d70c8bbf80d8869ad  Kotobattle-03.gb
db25f20e465cc3fbdd67f41a53317bec  Kotobattle-04.gb
46e389da50a2f7acd3dc72ceb8bc7a1d  Kotobattle-05.gb
55036e98f2c510d8f39641289e82e44d  Kotobattle-06.gb
0082fb3b7b0e008614be5e3689cc4a37  Kotobattle-07.gb
3890769be1f9a7595b070912fe198222  Kotobattle-08.gb
436b3fee8a7157b524aafd73347c3655  Kotobattle-09.gb
c3cb623adde261202af1dfe563666808  Kotobattle-10.gb

None of these match the expected hash of 43351CD46357BD1615A713490401FDA8. Across these ten dumps, a total of 251 addresses were dumped incorrectly at least once. Most of these (86 addresses) were incorrect only once, but some were incorrect most every time, often in similar ways. For example, 0x1C9738 was 0x03 (which is incorrect) in eight dumps, and 0x00 (which is correct) in the other two. Most of the time, though, the errors are somewhat different – like 0x0785FC, for which 0x00 is correct, which dumped incorrectly seven times as 0xFB, 0x02, 0x93, 0x02, 0xFB, 0x02, and 0x02. Another interesting pattern is that most of these errors (206 out of 251 addresses) occurred with bytes that should've been 0x00, which may or may not mean something.

The extremely weird part is this: Kotobattle has the exact same MBC (MBC5) – and even PCB (DMG-A08-10; pictures of an identical board here) – as another game I tried dumping, and yet, Kotobattle has random incorrect bytes while the other consistently dumps well. Dumping SRAM also works totally fine every time.

That the MBC and PCB are the same as for a working game suggests that it's a software issue, but the fact that the faults are so intermittent suggests a hardware issue. I'm deeply perplexed. Does anyone have any idea what the problem could possibly be?

My Retrode is hardware version 2.2, firmware version .25a-beta, and I'm on Windows 10.

Edit:
I've now tried reflowing the mask ROM and the MBC to no avail. The same mind-boggling symptoms persist. It's a bit hard to see any meaningful pattern (you can see the incorrect bytes from each dump collated here), but someone mentioned one thing: incorrectly dumped addresses with the same last three nibbles sometimes appear exactly twice. For example, 0x0907DC was incorrect 10/10 times, and 0x0AC7DC (also ends in 0x7DC) was incorrect 9/10 times – 0x5F0, 0xEBC, and 0x5C0 exhibit the same property.

At this point I'm almost considering a faulty ROM chip, but… I've never heard of mask ROM failing!

Can confirm Gradius III US is compatible with my Retrode.
