General Discussion / Re: Virtual Boy SRAM Support (FW v0.25)
« on: 18/Aug/2018 07:18:32 AM »
Pat1986 found a bug in FW v0.24a that broke support for Sega Genesis/Megadrive Sonic 3 & Knuckles.  The bug was related to the code changes that enabled reading Super Street Fighter 2.  I've fixed the bug and now both Sonic 3 & Knuckles and Super Street Fighter 2 work.

I've released a new firmware FW v0.25a with the fix:  http://www.mediafire.com/file/i2a1q7dft3f4135/Retrode-v0.25a.zip

Identified the setting that is messing up Sonic 3 & Knuckles.  An instruction was added to enable reading of SSF2.

I'll have to add some code to make sure both carts work with the same firmware.

EDIT:  Fixed.  Both Sonic 3 & Knuckles and SSF2 now work on the same firmware.  I'll compile a new v0.24 version with the fix and also merge the fix into the later firmwares.

Tested a Memory Pak and it reads out properly.  I compared the Mempak1.mpk dump against a dump using a different reader and the files matched.  I tested from the v0.18d (first firmware with memory pak support) up to v0.25.

Before attempting to read the memory pak, make sure your Config file [sramReadonly] or [saveReadonly] is set to 1.  Wannado mentions dumping your memory pak at least a couple times to confirm the contents before making any changes.

Refer to Wannado's Guide:  http://forum.retrode.org/index.php?topic=196.0

Yes, I tested Sonic 3 & Knuckles and it is broken in v0.24a.  The upper addresses are not completely dumped.

If you need to dump Sonic 3 & Knuckles, then use a firmware up to v0.24.

I'll look for a fix.

Diagonal resistor was on the older board revision.  V0.4 PCB places them vertically.

On another note, is there anything additional required to get Mempaks working in project 64, i.e. do they need converted or anything like .fla files? I soldered an N64 extension cord to the new N64 plugin and it picks up the Mempak from the controller. However when I test it using TWINE it says the pak is corrupted and forces a reset

Did you add the 220R resistors to the board?  Another poster was asking about connecting a controller to the plugin and I was reminded about the resistors.  They're 1/4W resistors soldered in vertically on the v0.4 PCB.

You can get an N64 controller extension cable and cut it.  Solder the wires to the plugin PCB.  You'll need to also solder 220R resistors onto the board.

Ok.  I picked up another copy of Pokemon Snap (U) with the 29L1100.  I initially could not get the save read properly.  I cleaned the pins and retested the cart.  The initial save data showed areas with incorrect (address) data.  I removed the cart from the plugin, reinserted it, and then tested the read.  After a few times of reinserting the cart, the save data showed up complete and intact.  My second copy of Pokemon Snap now reads out completely.

My suggestion to anyone experiencing save data corruption is to clean the cart pins first.  If the data is still corrupt, then remove the cart and reinsert it into the plugin.  The cart pins are most likely oxidized and may need multiple insertions to get through the oxidation.

The only additional wiring needed would be if you wanted to read Codemasters carts.

I've never worked with the Mempak so I don't know.  I'll try to run some tests later.

After I looked at the Pokemon Snap save, I vaguely recalled that another poster had mentioned problems with their save.

The previously reported problem was on a US Pokemon Snap cart.  The issue was exactly the same.  If you look in the save file at 0x8000-0xEFFF, that is not valid save data.  The data written is actually the block address that the Retrode is trying to read.

I could not duplicate the issue with my US Pokemon Snap (29L1100) cart.  Other testers did not report any problems with their carts.

I'm not sure why the two carts have issues specifically at those addresses.  It could be a power or timing issue related to the flashram chip.  Try connecting the Retrode to different USB connections and redump the save.  Check to see if the data at 0x8000-0xEFFF changes.

Good Luck!

The Donkey Kong save works for me in PJ64.

The Pokemon Snap save looks like it has correct save data but I couldn't get it to work after saveswapping the file.

Could you try reverting the Retrode FW to v0.23 or v0.23a and redump the Pokemon Snap save?

Good Luck!

Ran across an eBay listing for Game Gear slots:  https://www.ebay.com/itm/Game-Gear-45-pin-Slot/283019404463

In case anyone was looking for one and didn't want to pull one from a console.
