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
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
nice one H0ffman, I am glad you are aware of the TMSS issue, here is the flash PCB with SRAM you need: https://es.aliexpress.com/item/1005008591123623.html?spm=a2g0o.productlist.main.8.44216db7QQBTSp&algo_pvid=348f644c-f3e4-4e52-93ea-9d2dfe3647af&algo_exp_id=348f644c-f3e4-4e52-93ea-9d2dfe3647af-7&pdp_ext_f=%7B%22order%22%3A%2223%22%2C%22eval%22%3A%221%22%7D&pdp_npi=4%40dis%21MXN%21120.68%21107.90%21%21%2144.12%2139.45%21%402103246617484530063751688ef1b1%2112000045891054488%21sea%21MX%21862716286%21X&curPageLogUid=pDmq5CBZS5Nm&utparam-url=scene%3Asearch%7Cquery_from%3A
