From American Forums: I checked with Charles MacDonald and they should work just fine. If the PAL Mode is in fact needed, we can just add a switch to the PAL/NTSC input pin of the VDP to put the system into PAL mode... if the PAL video timing is needed. Apparently these TecToy games don't have any ...

i hope so i am eager to play these games. i know they werent the best the master system had to offer but damnit it's a sega game!

This is what I did earlier as explained with testing the BIOS.

To make it more interesting! SMS2 BIOS has v1.3 code! "Its checksumming routines seem to be taken from the US/European Master System BIOS v1.3 - they do not feature any of the later changes, and the $2 checksum range bug is not found. It is worth noting that this BIOS was only featured in Maste...

My personal theory on this, is because the v1.3 has no checksum range bug like v2.4 does it would have a better chance of playing Tec Toy 1mbit cartridge. I will not know for another week and I hope some one here has american console to let me know if this is true. I agree. I ended my read at SMS P...

This really should go into it's own topic at some point but here's how it all started. I had a v2.4 with Hang-On/Safari Hunt originally. I had Pro Action Replay (PAR) I always used with it. After some time the controller wire had to be in certain spot for it to work properly. I fixed solder on contr...

The funny thing is I had two. The one broke. The difference besides no game, according to SMSPower documents is that this original v1.3 BIOS has proper checksum code, in v2.4 (which is what every one else uses) a part is broken. So, technically v1.3 is superior to v2.4 code.

I have the earliest known BIOS. The one that includes no game. Was this ever released in Brasil? If so, can any one test these two games? I can probably find another v2.4 BIOS SMS1 (they were easy to find here in states, it's the most common model).

Alguém pode testar este jogo no modelo americano SMS1 NTSC? Algumas pessoas disseram este jogo e Blast Sonic não vai jogar no modelo americano SMS1 NTSC. Espero que isso não é verdade. Não se preocupe, funciona perfeitamente em qualquer Master System :mrgreen: Verdade com Sonic Blast? English: Basi...
