Support / Re: Phantasy Star IV SRAM data compatibility with the Retrode2
« Last post by Nori on 25/Mar/2018 06:24:51 AM »
In the past I lost data in save 1 and 3 but 2 always worked. I haven't tried recently but maybe 1 and 2 now work.

General Discussion / Re: SEGA SMS/GG Firmware (FW v0.24)

There appears to be a bug introduced in this firmware.  The bug is with reading SFC/SNES Nintendo Power carts using my Enhanced Cart Adapter.  Using the HWB button to cycle through a multi-game NP cart no longer returns you back to the Menu ROM with the flash map files.  It is an odd bug because I didn't touch any of the SFC/SNES code with this firmware.

I'll look for a solution.  In the meantime, anyone reading NP carts should use firmwares v0.22, v0.23, or v0.23a.

EDIT:  Looks like I'll need to disable the display of the NP Flash Map files going forward.  The Flash Map files are causing I/O issues that result in the Retrode hanging.  By disabling the Flash Map files, the multi-game cycling using the HWB button works as expected.  I'll keep the underlying Flash Map code in the firmware in the event that a solution is eventually found.

Finished SSF2 support.  I'll roll it into a future firmware release.  I'm contemplating an update to the current v0.24 SMS/GG firmware.  If I release a v0.24a firmware then the SSF2 fix will be in there.  Otherwise, the change will come after the upcoming Virtual Boy and PCE/TG16 firmware releases.

Looks great! Can't wait to test one out.

My revised prototype plugin PCB with support for Street Fighter II' arrived.  The PCB adds control of /WR to enable the SF2 mapper.  SF2 support requires using my PCE/TG16 firmware which will most likely be released as FW v0.26.

Interesting Retrode bug.  If you read the SSF2 cart on the Retrode, at the odd addresses 0xF1-0xFF, you'll see the current bank map (repeats every 0x100 bytes).  The Retrode's Sega read code is reading the SSF2 bank registers 0xA130F1-0xA130FF instead of the ROM data.  The odd bytes at 0xF1-0xFF will be 00,01,02,03,04,05,06,07 which are the banks mapped to Banks 0-7.

I might change the SRAM pinout that was posted as I was asked to support Hyper Fighting.  In order to read out Hyper Fighting, I need to free up pins on the Retrode to connect the uppermost address pins on the VB.  Right now, the uppermost address pins on the Sega slot are used to control the VB SRAM.  I didn't want to use them for addressing as the Retrode uses those pins for configuring other cart types.

I'll have to do more testing to find the best pin configuration.

This looks excellent! Are you going to sell these or offer the schematics up for download at all? I'd be happy to help test in any way I can.
