Okay I just had a very bad experience with the DEMO of Demons Of Asteborg on my Mega EverDrive X7.

My story should keep you lot away from it, if you want the game just buy it on a single cart from the proper shop.

I downloaded it as it was for free as I was curious to what everybody was raving about, I did notice it was 14 Megabytes big when I downloaded it (which is over the 10 Megabyte limit) but was too curious, so I boot it on my Mega EverDrive X7, and it first gave me a message saying the SRAM is corrupted, when I got past that screen the intro was extremely buggy with lots of graphical artifacting, then the title screen came on like nornal, I pressed start and then got a black screen that never ended.

I don't really care about this game to be honest or whether it runs on the X7 or not, it's what happened after that is what frightened the hell out of me! After booting Demons Of Asteborg I went back to play some other ROMS and they all crashed! I tried booting many common Mega Drive games such as Sonic The Hedgehog, Jewel Master etc and half of them crashed on the ''PLEASE WAIT'' screen before the game even finished loading. Others gave me an SD card error screen, while some booted but crashed as soon as I brought up the in-game menu. It even crashed on the ''run diagnostics'' test screen not finishing it's test. My adrenaline was pumping and my anxiety was flaring up because your immediate response is ''oh shit it's f--ked and there's nothing I can do!''

Anyway it seems to have ended well, I took out the Demons Of Asteborg ROM from the SD card and after that the X7 went back to normal, I was able to run diagnostics without a hiccup, games loaded and games functioned properly with the in-game menu brought up in between gameplay. Even Ultimate Mortal Kombat Trilogy worked again so that retard Demon demo of a game was responsible for the bugs and crashes on the X7, it wasn't until I removed the ROM entirely that the X7 worked properly again.

So my experience was almost life threatening because these EverDrives are not cheap were I live and buying another one and having to wait til it gets shipped over here takes far too long especially during this never ending Groundhog Day Covid-19 Delta apocalypse that never seems to end and i'm in lockdown and have been for nearly 3 months.

So take it from me, DO NOT DOWNLOAD THE ROM TO PLAY ON THE X7, its not designed for it, it exceeds the 10 Megabyte limit of the console and the X7 is not designed to handle extremely large games that are made with different technology of 2021 and beyond.

To be fair it is partially my fault for letting curiousity get the better of me. When it comes to Paprium or Demons Of Asteborg there is no other option but to buy the games on single carts from the online shops, even watermelon's Pier Solar doesn't run.

And to think it was only the demo. The full game might have exploded my Mega Drive!

Wow what a nightmare! But I really doubt that a ROM could actually damage the Everdrive, the worst thing that I think could happen would be a corrupt SD card and possibly the boot loader. And the limited ROM size of the X7 is claimed to be 15MB not 10MB, so the reason it doesn't work on the X7 must be something else unless I missed something.

I bought my X7 a very long time ago back in August 2015 when it was the top EverDrive on the market and on the back of the case and in the stonage gamer manual (which is where I purchased it from) it clearly states that 10 Megabytes is the limit. That's why ''Ultimate Mortal Kombat Trilogy'' doesn't run once you add the music patch to it bumping it up to well past 10 Megabytes to 13 Megabytes resulting in a black screen.

I have always looked after my X7 all these years and have never had a problem with it. This was the first really horrible experience i've had with it. True, it could have been an SD card corruption but when I checked the card on the PC there were no issues detected. It may have damaged the boot loader like you pointed out. All I know is that once I removed the ROM entirely from the SD card, the X7 went back to normal, so Demons of Asteborg gave it some sort of negative reaction.

 Hey ho. I bought the New game Demons of Asteborg.
I hexedit the header DOA to SSF at the beginning of the file, game starts and is playable but with an SRAM ERROR shown by start of the rom. No savegame possible.
Do you bring out a solution for this issue also on the X7 ?
Doa mapper implementation isn’t planned for x7, at least not in near future

yes because now he want to sell the pro version that supports it, who cares of the milions of people that have mega everdrive 2 and x7 that costed 170$ to buy it. Its ended the period where krikkz firmware updates where always fast, and edn8? forgotted to, last fw is a beta...

full game working fine here but can't save. even if the demo gameplay play prompt a pirate message...isn't the game programmed to be compatible with mega x7?  so why a fucking pirate message?

Millions, haha. Definitely not, but it is for sure, one of the reasons why I haven't bought any of Krikzz's products since the GBA Everdrive, and never will again. He's getting lazy and greedy. I find Terraonion products to be of a higher standard, anyway.

It's not supported on the X7 and Krikzz has essentially said he has no intention of updating them to be compatible, which you have already found out.

Krikzz should still offer some minimum support for the X7 like finding ways to fix already existing bugs like why the X7's battery back-up saves never seem to work properly on ''Megaman The Wily Wars'' and ''Wonderboy In Monster World'' even when following the correct prompts like reseting back to main menu and as far as I know the Megaman and Wonderboy EPROM saving issue has been going on for 7 years now and the latest firmware still doesn't fix it. I can understand these unlicensed large indie games with different chip sets in them not working on the X7 like Paprium, Pier Solar and the evil Demons of Asteborg which gave my X7 some sort of virus for a short time, but I don't think he should just toss the Mega EverDrive X7 on the scrap heap. These flash carts are still quite expensive, well at least here in Australia they are because of shipping and import taxes slapped on plus the currency rate is much lower here so a $170 US dollar X7 from the Krikzz store easily rises to $300 AU.

If he chooses not to support the old X7 series, at least lower the price a little I say as a done product. Pro does nothing for me i'd personally rather use a real Mega-CD attachment and burn CD-Rs. There's been far too many issues and problems from people of the community having trouble trying to organise folders and how to play ISO/bin files in cue folders with WAV and MP3 music files etc. I couldn't be stuffed with dealing with all that, X7 all the way with real Mega-CD add-on so I can just pop any music CD in the tray and be done with it. (Just my opinion of course) not trying to piss anybody off who owns a Pro.

Ok so the ROM memory size must have quietly been bumped up at some point.
I meant that the worst kind of permanent damage that COULD happen is data corruption in the storage memory, the SD card and bootloader, which would mean loss of save files. Thankfully that didn't happen either, it was just a scary experience from a bug caused by loading a ROM larger than supported.


I agree with you and I rather use my real Mega CD with burned discs than playing CD images on the Pro. The CD support is just a bonus, and as a way of saving on CD-Rs when doing a lot of testing, especially for homebrew development. But no matter if I use the Pro's CD support or burned discs, I wouldn't touch an ISO that's using MP3 with a ten-foot pole. Only perfect 1:1 dumps thank you.

milions is intended as "many" non real milions lol

the game is x7 compatible because one of the developers said that, on sega16 forum.
Also for krikzz, add mapper support, already present on the pro, it's a matter of 5 minutes...maybe he already forgot how much was the original price of a X7.

Yes, but it can't save. The game is playable, not fully compatible.
