You're welcome.

I'm using programmable carts from ali express that have battery backup.

They work great.

I've played the game through.

Edit:

Systems tested - mega drive 2, mega drive 1 VA1, MegaSG, Genesis 1, Genesis 2.

I have done the same, battery backup aliexpress, it leads to a black screen on boot all my consoles, only the sega genesis model 1 (without TMSS), you have tested on PAL and NTSC right?

xchester77136 days ago

I have no way to test PAL.

This is what my cart looks like.

Now the I've looked at AliExpress carts, I actually don't know where I got it cuz it doesn't look like a typical AliExpress cart.

It looks like those xxx in 1 game carts they sell in AliExpress, Amazon, and eBay but I've never bought one of those.

I made another cart on a dragondrive and it seems to work as well:

I just used the dragondrive as a test because that cart is usually cave story.

Same here, i just tryed with this board (2mb with save), just a black screen O.o (tryed on a japanese mega drive without region lock)

it is confirmed that the game has issues with TMSS consoles, it will be fixed on the next release, the issue is not on your cart but on the game.

I tried these two models, none of them worked withTMSS consoles, mine are NTSC america, I will try with another flasher program, thank you for your help

xchester77136 days ago

I have some non-battery 4MB carts.

I'll try 1 later today.

diablonet135 days ago

excellent, please, I tried another flasher but same results, so maybe the issue is on the flash cart, I will wait for your results, thank you in advance.

I programmed this card and it worked on mega drive 1 and mega drive 2.

Do other games you are flashing work?

Hello, I made 2 videos, look at them, on my case the issue seems to be related to TMSS. On the Genesis 1 without TMSS it works just fine, on the Nomad with TMSS it doesnt. Same behavior for flash cart with or without battery. thank you for all your help.

xchester77135 days ago

Very interesting.

My mega drive 2 is TMSS and it works fine.

I'll try a TMSS Genesis.

I did some testing and my results are the same as yours for all my American systems with TMSS.

I originally said I tested Genesis 2, the was a mistake. I thought I tested the standalone cart there but I must have been mistaken. I apologize.

Here are my full results:

1x Mega Drive 1 no TMSS - working

1x Genesis 1 no TMSS - working

2x Genesis 1 TMSS - not working

1x Mega Drive 2 - working

2x Genesis 2 - not working

1x Genesis 3 VA1 (mod to support 32x/CD) - not working

1x Genesis 3 VA2 - not working

All Genesis 2/3 and Mega Drive 2 have TMSS.

So, North American systems with TMSS are not working.

It's possibly something in the code.

Hoffman might be interested since it impacts flash carts too.

Hello, thank you so much for confirmation, it was so frustrating for me, because it seems to be working fine for everyone but me, I am not sure if it is a bug or a protection system, because of the boot message "Dont buy carts from ali express" and the only way to play it on original consoles (like the majority of my consoles) is using a flash cart. But I am glad that you confirmed my TMSS suspect, I also double checked the rom header on $100 looking for SEGA text, but it is there, so the doubt is, BUG or FEATURE, maybe on version 1.2, I already posted about the TMSS issue on the comments, but no reply from H0ffman so far. thank you again for your help, I can relax now :D
