I have done this with V3.5. Updated the retro-pie script, then did an apt-get update and apt-get upgrade (or dist-upgrade, don’t remember which). After those finished, I pulled the SD card from the 2 and put it in the 3. Worked like a charm…

I’d still back it up, though. Just to be safe.

More than likely, your issue with the rom is a MAME version mismatch. Mame4all uses MAME 0.37b5 (which is quite old). See the guide here:

I can attest to 128G SD cards working fine. I have 2 of them, one in my pi2 and one in my pi3… Both work great, although I can appreciate not having to copy all the roms over every time I rebuild the SD card…

Last time I had a marquee printed I used mamemarquees.com (now gameongrafix.com). Worked very well. They have several pre-canned ones you can choose from or you can upload your own. You pick the size and if you want plexi cut to fit as well…

[jsawhi]

yup… (and make sure to re-read my edits as I added more info)

Not sure why it seems to be such a quiet subject. Maybe they want you to purchase the controlblock instead?? *shrug*

I had the same issue. While it can be done (I did it for my SNES case), I had to solder a couple of pins to the powerblock (see this post: https://www.petrockblock.com/forums/topic/snes-gpio-config-with-power-block/)

Using a different power controller would probably be your best best if you don’t want to solder or do anything like that (and if you live in the US will be cheaper and arrive faster than from overseas).

That said, I have a Mausberry power controller in my N64 conversion console. While it works, it seems a bit more no-frills vs the powerblock. It works, but it’s basic. no LED indication of what’s going on (power up or down), have to solder a pin in for the LED, not a service that runs, just an endless loop script that polls for the switch to send the shutdown command. I like the powerblock better (and it supports the project). The ATXRaspi is another power controller I have in my C64 conversion (yeah, I know) and I like it, but it only works with momentary switches so not a good fit for the SNES/N64 case.

The old X-Arcade sticks with only the serial/PS2 adapters do work with the PS2 to USB adapter, *HOWEVER* you have to have a PS2 keyboard plugged into it (then it plugged into the adapter) for it to function… You also have the option of buying an upgrade kit for your stick (which is what I did on my first gen SOLO stick):

Once you put that board in, it shows up as a USB keyboard that you can program without issue (or need for a separate keyboard)

ok, so I decided to try the gamecon_db9 driver instead…. In it it showed that I only needed 2 of the pins that the powerblock were connected to (using pins 17 and 20 for vcc and gnd). So I just soldered 2 pins to the top of the board and connected to that. All seems to be working like that. Didn’t want to have to do it that way, but it is what it is…

Would be nice if there was a way to make this work with the powerblock without modifying it…

I also noticed this on 2 SNES original controllers on the mayflash SNES to usb adapter. When I use a keyboard, there is no delay.

[jsawhi]

odd… I have 2 of the x-arcade solos (one internally configured for player 2, so I don’t have to sit that close to the other person playing ;) ) and both work fine out of the box as keyboard devices… I essentially have 3 keyboards connected to the Pi (actual KB, and 2 separate solo sticks). I know the board is the same in the solo as it is in the dual tank-stick… not sure why it’s timing out. *shrug*

(sorry, not adding much, but at least you know it can work)

[jsawhi]

I have one of those in my SNES console (granted, taken apart and directly connected to the SNES ports, but same principal). They work great! I do notice a ever-so-slight delay (maybe 5~10ms) in reaction time on this however. I’m trying to run my SNES controllers via the GPIO (to no avail yet) to see if that’s any better. When I control a game with my keyboard there is 0 delay.

But all in all, yes it works. Plug and play (no config or drivers needed), and it recognizes both controllers separately.

[jsawhi]

I think I answered my own question about why it’s used after digging around a bit. The GPIO pins use 0V or 3.3V, not 5V. I would assume if the controller was powered with 5V, the data stream would be at a 5V “on” level.

Still may be the issue on some controllers not working well at 3.3V instead of 5.

[jsawhi]

I really have no idea if this matter or not, but I’ve always wondered why the GPIO adapter seems to use the 3.3V pin instead of the 5V pin to power the SNES contoller… According to pin out diagrams, the actual console outputs 5V on the Vcc pin. Maybe that’s the difference? *shrug*
