SMS roms with Mega Everdrive Pro on Mega Sg
« on: January 25, 2021, 09:40 AM »
I'd greatly appreciate any help. I've searched through various posts on here and other sites with no solution or understanding what's causing this problem.

I created a SmokeMonster ROM pack for my Mega Everdrive Pro.
I've been able to get NES, Genesis, and Sega CD ROMs working, yet I cannot get a single Sega Master System ROM functioning on my Mega Sg. It remains on a black screen when I select an SMS ROM.
I've formatted the 400 GB genuine SanDisk Micro SD card in exFAT and 256kb allocation unit size.
The Megakey setting is set to OFF.
I've tried with Mega Sg v4.7 firmware, and also with the jailbreak v7.7 firmware. No luck.
I've tried smaller micro SD cards in exFAT and FAT32 formats with only SMS ROMs.
I've tried with and without several different SMS BIOS files in the MEGA/bios folder.
There was a solution in 2019 about first selecting the SMS ROM, running Ultracore, then returning to the cartridge. Didn't work for me.

It's clear I've overlooked something. If anyone can make any suggestions, I'd be grateful.
Thank you.


*****UPDATE: I tested the MED Pro on a Sega Genesis Model 1. I was able to play the SMS ROMs. Therefore, I've concluded the problem lies with the Mega Sg. I'll follow-up with Analogue.

Are the SMS roms also from a SmokeMonster or no-intro pack?
What is the file extension for your SMS roms? I think it should be ".sms".
The roms can't be inside the MEGA folder.


If nothing works it might be a problem with the Mark III mode of your Mega Drive. Does SMS games work using a Power Base Converter or similar adapter? The Phantasy Star 1 MD cartridge also counts as an SMS game in an adapter, if you by any chance happens to have that game.
Try cleaning the console's cartridge slot with isopropyl alcohol. The Mark III mode pin might be dirty. Check so there isn't a resin blob or anything on the Everdrive's connector.

Thank you for responding and offering help.

The SMS ROMs have the correct ".sms" extensions and are not in the MEGA folder. I created the Master Everdrive version of The SmokeMonster packs and everything was verified through it's script.

Do you mean that you believe the problem may be in my Analogue Mega Sg? I don't have a Mega Drive/Genesis. I received the console last year, yet I finally took it out of the box to test earlier this week to enjoy.

When I arrive home later, I'll follow your suggestions by checking the pins on the Everdrive connector. The Everdrive is also new. I'll also check the pins on the console as well.
I'll pick up an SMS cartridge or the Phantasy Star you've suggested.
I guess I'll look for somebody in my area that can test my MED Pro on their Genesis/Mega Drive console. That might be a challenge.

I missed that you had a Mega SG. Yes that's probably the problem. Everdrives often has problems with modern clones.


Both the console and Everdrive are so new that I doubt the pins are dirty already, but I remember before that someone had a drop of resin on their Everdrive from the production.

The Phantasy Star game is a Japanese exclusive and not cheap, so it's a bit much to pick up just to test with.

Can you tell me what you've done?
Did you  install a firmware in the MEGA/bios folder?
Are you using SmokeMonster Everdrive packs?
Anything information would be grateful.

I've checked the pins on the Everdrive cartridge and in the Mega Sg and they're all pristine. There's no discoloration or visible residue or imperfection.

I've read there's quite a few Mega Sg users. Some have had issues due to software, bios, or micro SD card. I'm thinking this is a software issue of some kind.

I reformatted the micro SD card using SD formatter. All the ROMs work fine, except SMS. Even tried the SMS ROMs using the cores of the console with no issue. I'm stumped.

Still no luck.

1. Mega Everdrive Pro Settings
* Options: Megakey: ALWAYS OFF
* Options: SMS Bios: Tested OFF and on
* Options: SMS YM2413: Tested OFF and on
* Previously tested with OS 4.08, NOW tested with OS 4.09
I'll have to look up about returning to OS 4.08 and redoing it in that OS.

Mega SG settings
* Video: tested in 720p60 AND in 1080p60**
* Startup Options: Title → Cartridge [done]
* Hardware: USA (NTSC Export)  [ALWAYS used this setting ON]
* Hardware: Auto Region Detection (when game fails to boot ) [ALWAYS used this setting ON; tested with OFF as well]
* Buffer Mode: Zero Delay [ALWAYS used this setting ON]

* Buffer Mode: Single Buffer [tested with this setting on]
* tested with Firmware JB 7.7

2. no sms bios used, ever
3. This set was downloaded and used, along with SmokeMonster pack
4. The SMS ROMs from BOTH SETS run on jailbreak v7.7 in the Mega Sg SD slot. Makes sense they work since almost two thirds of the SmokeMonster ROMs are made up of the no-intro set you recommended.

*** Of note: I'm using a SANDISK 32 GB micro SD card formatted in FAT32 using SD Formatter. ROMs run properly with MD/Genesis ROMs.

Sounds like you got a dudd! Either your Pro, Mega SG or Mega SG firmware is broken.

Why don't you try Mega SG firmware 4.6? 4.6 is better than 4.7 4.7 has an issue with SMS games with the zero lag zero delay option, every few seconds there is a judder in the frame rate when running SMS games on 4.7 in zero delay zero lag buffer option, 4.6 doesn't have this issue and runs perfectly smooth and just maybe it might run sms games for you.

It's worth a try, nothing to lose.

Thank you for the suggestion.
I've tried firmware version 4.3 up to 4.6 now. Used the default selections. Cycled through SMS Bios OFF/ON and SMS YM2413 OFF/ON.
Still no luck. Everything else was running.

Maybe one of the FPGA items isn't running properly. I'll have to find someone with a Mega Sg and a Genesis in my area to narrow down the dud.

There is not need any special tricks to play sms games on everdrive + mega-sg. It should work with any combination of options and with or without bios files. I suspect that sms mode broken on your cart or on your console. The only way to check where the problem is try another console or another cart.

Thank you for the response.
I'm working on finding someone with a Genesis console to test my MED Pro on.

I've tested the same SMS ROMs on the Mega Sg. (using the jailbroken BIOS) and the ROMs work.

I decided to purchase a Genesis model 1. I tested my MED Pro and confirmed the SMS ROMs function properly. Therefore the problem lies in the Mega Sg. It won't run the SMS ROMs.

I'll contact Analogue and see what they'll say. Thank you for your help.

This is an old topic, but you need to disable the BIOS setting in your Mega SG in order to get SMS games working on your Mega EverDrive Pro:

1) Attempt to load a SMS game on your MEDP and get the black screen.
2) Go into the Mega SG menu then navigate to the "Core Options" section.
3) Untick "use BIOS" & save your Mega SG settings.

Optional:

4) Download SMS BIOS of your choosing, rename it "smsbios.sms" and leave it in the /MEGA/bios/ folder.
5) Turn on SMS BIOS feature on MEDP and you'll have a BIOS load before your SMS game.

Looks like it might be some sort of conflict between the two devices.  Hope this helps!
