Freshly built PI Zero..plays NES and SNES fine so far. However Sega is slow and laggy to play.

Im new to PI's but not too green with emulators. I built this off using these instructions https://howchoo.com/g/mti0oge5nzk/pi-cart-a-raspberry-pi-retro-gaming-rig-in-an-nes-cartridge

Im using the 4.0 Retropi image and whatever Emulators came bundled with it. So far all of the NES games and SNES ive tried play perfectly. I've tried a few Sega games (Sonic mostly) and it plays but it is slow and kinda ruins it.

I unplugged my USB Hub and did a direct connection with my USB SNES controller but its still acting the same way. My power supply was this one http://www.ebay.com/itm/141518809160?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Output -- 5V, 2000mA max

Im gonna look around the office to see if anyone has anything else for power supplies I can try out. I see in the Retro PI's menu I cannot overclock it but is that even a fix for this or is it a bandaid?

Any advice is greatly appreciated as I love me some Sega games.

Not sure what the "Sega rom folder is" Do you mean Megadrive / Genesis or Mastersystem or Sega 32x or a sega game on another platform ?

To find out the emulator

Seems to be two possible errors.

Use annother emulator ... For MegaDrive/Genesis (and Master System?) - lr-picodrive is the better choice
Don't overclock your Pi Zero, even if it is close to a Pi1 - you slow your system down!

So you guys helped me fixed right off the bat.

I had no clue that triggering it to create a log while launching a game would show a menu to change emulators.

I was using 'lr-genesis-plus-gx'
Switching to 'lr-genesis-plus-gx' seems to have solved the issue.

Everything plays much smoother for Genesis games now

Thank you all

I am having the same issue and went to LR-Picodrive but still the same issues ( on raspberry pi 3b )
NES and SNES working fine.

graphic glitches (hanging textures and few hanging frames etc etc etc . )
Built on retropie 4.1 with raspberry pi 3b
