A few bugs I've encountered while playing the game: 1. Hyper dashing as Hyper Sonic in Sand Shower Zone near badniks or monitors crashes the game. 2. Entering and exiting debug mode as Miles in Sonic 1's special stage crashes the game. 3. When the Sonic 1's special stage is enter from the level select, exiting the special stage by either start+a, ...

Hi, I know that sounds a bit lame but... Has anyone a code for unlimited continues/lives? When you lost all lives and continues. You can load the last played level with 3 lives from Save Select Menu. And you can get extra lives entering on bonus stages through lamppost. Hitting a lamppost with 20 or more rings allow you to play a bonus stage where...

The game require full SEGA Mapper support to work.
Error $40 - "Mapeador não inicializado" - Means SEGA Mapper not supported by device.
Error $41 - "SRAM não inicializado" - Means SEGA Mapper is supported, but without SRAM Support.

..... because I doubt mode 0 works on all consoles. I have various revisions of Genesis / Mega Drive and the game worked without any issue in all of them. Tested in Genesis 1 VA3 (without TMSS), Genesis 1 VA7, Mega Drive 3 (SEGA 315-5960), Genesis CDX, Mega Drive 2017 (Redkid 2500 processor) ( I have other consoles revisions, but I think that is e...

So yeah, the memory contents that I posted before do match if I play a sound above 33 before entering the Super Debugger. I checked the banking and it looked as you described, except that bytes were duplicated in SRAM (so "NNEETTOO" rather than "N E T O"). But this probably has no connection to the banking mechanism and seems t...

Just tried the new version .44 and now it does not start at all on the MiSTer. Just shows this debug screen sonic.JPG The last version test if full SEGA Mapper is available and throws exception $40 if ROM mapping fails or exception $41 if SRAM mapping fails. If you have an Everdrive of X-Series you can try a modified O.S. ( https://www.neto-games....

I made a change to enable the SRAM banking and ROM banking at the same time and it seems to work, but I still don't understand what's happening with sound. Oddly, it seems to work fine on the Data Select screen but is broken (sometimes static or distorted sound but usually just silence) elsewhere. I think this isn't due to my SRAM banking change b...

I have asked Krikzz and the new ED-MD Pro will have support.
P.S. I have downloaded a copy of the O.S. of ED-MD Pro and I could see a reference to my hack in the file "megaos.dat".

Hi, I am developer o Sonic Delta 40Mb rom hack. The last releases ( https://www.neto-games.com.br/rom_hack/sonic_delta_40_mb.php ) are running without any issues in real hardware. The bank switching scheme used in the game follow SEGA standards, as you can see in the page #51 (copy in attachment ) of this doc ( https://segaretro.org/images/2/27/Gen...
