Title: Glitches around sprites. Defective Mega Everdrive X7?
Post by: Skooter on April 16, 2019, 05:13 AM
I have a Mega Everdrive X7 and I'm noticing glitches on some games, usually around the main sprite.

For example, take a look at this Tanglewood video, running through Mega Everdrive X7 on my Sega Genesis:

I thought my Sega Genesis was dying, but I just bought a Analogue Mega Sg and I found the same issue. Please look at this The Revenge of Shinobi video:
https://youtu.be/4QCklJSP1MU?t=162

I loaded the game a few times through Mega Everdrive X7 with and without ingame hooks, and a few times through the Jailbreak firmware. The glitches only happened when loading through Mega Everdrive X7.

Since it already happened with both my real Sega Genesis and with the Analogue Mega Sg. And since it doesn't happen when loading ROMs with the jailbreak firmware. Is it possible that I have a defective Mega Everdrive X7?

Really strange!

Have you tried to clean the contacts of the cartridge well?
Are you sure the roms are ok?
Are they from a reliable source?

Yes, after these videos I cleaned the contacts with isopropyl alcohol.

The glitches didn't happen after that, but it's early to say they're really gone since the problem was always intermittent.

My ROMs are from No-Intro and SmokeMonster packages.

Tanglewood I extracted from the Steam version.

Now I can tell cleaning didn't fix it.

I started the game (Revenge of Shinobi) from Mega Everdrive X7 and just let the ninja standing there in the first screen without moving. After about half an hour the glitches started again.

Now I'm doing the same with the game running with the Analogue Mega Sg jailbreak, just to be sure.

Ive had a console that after getting very hot starts having weird graphical glitches, but it was with original cartridge. Can you try with Sonic 3 & Knuckles?

It seems a defective Everdrive to me, for it to happen with the Mega SG.

1) Mega Everdrive X7 on Analogue Mega Sg: glitches
2) Analogue Mega Sg with jailbreak: no glitches
3) Mega Everdrive X7 on real Sega Genesis: glitches

Thank you very much for taking your time to record it.

My guess is that your cart is bad. Wait for more answers here to confirm.

For sure something wrong with your cart, may be defective memory chip. You should send it back for exchange.

I'm under Stone Age Gamer 3 year warranty.
But they don't have Mega Everdrive X7 in stock now and it will cost me a lot to send it back. :(

Another Mega Drive, just to make sure:

And now the Mega Everdrive X7 is on the way back to Stone Age Gamer.

~ US$ 32 to ship it back and I'll still have to pay for them to ship the replacement.

Ouch, my X5 came from Stone Age Gamer too, but my sister's friend received there and came back to my country with it.

I hope this will sort it out the issue.

Maybe hacks? I saw you had unlimited Kunai's in the shinobi game could may have copied one too many strings of codes that gives that odd prepixel effect on the Shinobi sprite. As for Tanglewood it seems like a Everdrive issue.

It's not a hack. This cheat is available in the original ROM.
