I just got that too! I have been using Fusion all along, but without a BIOS file.The time in which it takes to change into your font may be the same amount of time when I mentioned " the TMSS will flash" and freeze with the TMSS showing.

No dice. Booting your ROM does the same as I described before.
I will admit though, in an emulator it is looking damn fine!

Played around a bit. Fixed checksum and fixed region support with uCON64, edited "genesis" to "mega drive". Nothing worked.
I believe your header is correct, or at least fine as is.

I suppose I also should have said "EEPROM" anyhow. Also, do you think you fixed the hardware bug in v004? Keep up the good work!

I'll test anything you throw out there. I don't have an everdrive, but my flash ROMs work just the same. Cheers

I just tried v002 on my Sega Genesis 3 and the TMSS shows up, flashes once and then stays on that screen. The tracker never shows up. I will try the previous version of your ROM and let you know if that works... EDIT: No, the first version does not run properly either. To be more descriptive, the TM...

Nice work. I'll slap it on a cart and upload a pic of it on real hardware for you. There should be no differences since it doesn't really do anything yet. :P

Shameless plug: My emulator Exodus has an "Active Disassembly" feature which was designed for exactly this kind of task. It uses information gathered about the actual execution of the program at runtime, paired with some prediction features to trace code through branching structures that static dis...

Disassembler/ Reassembler

I need to find a program to disassemble a Genesis Homebrew into Assembly , allow for modifications and then be able to reassemble it for me. Where can I find one? I have read about IDA Pro and 68kd, but the first is not free and the other may cause problems differentiating between code and data. Say...

Find the Mistakes

Electronic Arts has been my worst nightmare while I was trying to redesign higher-memory-addressing Gen/MD carts in Eagle CAD because of the single sided solder pads and the fact that opening their special carts always ends with a broken shell! Ugh... How many mistakes can you find on this cart? :lo...

I know how to make logic, but I'm not sure anything related to SRAM and RAM including EEPROM. If you know how to make logic, then you should have no problem. All you do is place the ROM and SRAM anywhere inside of the memory map as long as they don't overlap. Most commonly, you will use !CE and the...

You can even goes up to 10 MB... but indeed that break addon (sega-cd et 32X) compatibility. Yes, but it's much harder than 8 MB. Can I ask a little offtop question?) How I can add additional RAM (not SRAM) into cart?) Ofcourse with banking system or other tricks. This is in case if 65 KB RAM is ju...

I think this topic is more indicated in the hardware section of the forum ;) I see that now, thanks. :P The cart area is 4MB, it is totally up to you how you partition that. !LWR and !UWR can be used as you mentioned. Excellent. Thanks for that assurance. Now, were the two pins !LWR and !UWR ever u...

Unfortunately the SoC console designs seem to have given way to the "Let's use dog s--- emulation on an ARM and call that a console" approach. Which is really a shame. I mean the emulation is truly terrible. I can get better results on a Raspberry Pi using free software. Better results, maybe, but ...

Genesis / Megadrive Maximum Memory Map

I can't tell if we discuss the 16-bit Sega Consoles, but I am in need of some direction. I am trying to design a developer's cart that includes two or four 8-bit EEPROMs and the maximum amount of RAM that the console can access. http://i.imgur.com/FAnnHN9l.png I really only need to worry about 1 or ...
