 |
|
Does anyone have a list of which games are compatible? I read this in an SMD FAQ:
The banking scheme is not fully compatible with the type of memory mapping
used in some SMS and GG games in the following ways:
- ROM bank #1 is not present
- ROM bank #2 is not present
- Battery backed RAM pages cannot be mapped into ROM bank #3.
- ROM bank #3 will be set incorrectly if any address within $E000-FFFF
is written to.
I've converted a few to SMD format, but the games I've tried don't seem to work. Here's an example:
Super Com Pro/Super Magic Drive/SMD
000081f0 54 4d 52 20 53 45 47 41 00 00 ed b2 09 51 00 4f TMR SEGA.....Q.O
Sega Master System(II/III)/Game Gear (Handheld)
U.S.A. & Europe
131072 Bytes (1.0000 Mb)
Padded: Maybe, 2191 Bytes (0.0167 Mb)
Interleaved/Swapped: Yes
Backup unit/emulator header: Yes, 512 Bytes
Part number: 0x5109
Version: 0
Checksum: Ok, 0xb2ed (calculated) == 0xb2ed (internal)
Search checksum (CRC32): 0xd8c4165b
Data checksum (CRC32): 0xce8a948f
Any info would be appreciated.

uCON64 2.0.0 Win32 ver.
I'm starting to wonder if my SMD800 memory is flaky or even the floppy drive.
A few games, when loaded, booted up to a red screen. I thought it was the rom, but I tried copying from an original cart to a floppy and it still gave me a red screen. When the games do load they work fine though so idk. I have to do more testing with it.
I mostly wanted to try Sonic 1 MegaMix v3 on the real hardware.
I converted it to SMD format, then fixed the checksum:

| I can't recall how I converted ROMs...I've only played the SMS games on my MD+, never my SMD. Do you get issues when loading from LPT port or just off floppy? If you backup a cart to RAM, does it always play properly? That might narrow down the issues to either memory or FDD. |

| Lots of games crash after loading... Did you try resetting? I remember most of the SMS catalog being playable, the exception being games with WRAM like Phantasy Star. |

I am only trying from floppies for now (new floppies formatted to 1.6).
I am using a goodset of SMS roms that I convert to SMD using ucon.
I had some issues with other games, but I believe it was because I had lowercase letters in the rom name. so for now I have named them to SHINOBI, DOUBLEDR, etc.. No extension either.
Here's the thing, when I load them, the counter starts at 90 and goes down to 70, then says LOADERRO.
Probably a stupid question to ask now, but I don't need the Sega Power Base Converter to be connected between the Gen and SMD800, right?

I don't think your files are converted properly.
And no you don't need the PBC, it wouldn't even fit together. |

Try using the GG2MD utility. Also, I'm not sure if ucon expects a .bin (headerless) file for the SMS files or if it's expecting something with some sort of emu header. As I recall, you do need to reset the Genesis after the SMS games load.
As kyuusaku pointed out, it appears your files are not converted properly if the loading craps out like that. |

| We should start a list of SMS games that work with the Super Magic Drive. I have a Super Magic Drive and Super Magic Drive plus, so I volunteer to test both. |

I started with roms from the 20080210 NoIntro set and converted to SMD using Ucon64 2.0.0 (win32). They were originally in Multi Game Doctor (2)/Multi Game Hunter/MGH format.
I'll post a couple examples.
Please let me know if you see anything wrong with these.

| uCON64 is displaying the INTERNAL SEGA header, the problem is in the SMD header. |

So can uCON64 not create the correct header when converting SMS to SMD? Or is there a different switch I should be using? I'm using the uCON64 FE by the way.
Madman: I thought GG2MD was to convert GG roms to SMD format. Wouldn't that mess with the color pallet on many SMS games?

| No. GG games show up on a TV w/bad colors because of the difference between the GG LCD and a real TV. The converter doesn't do anything to the colors, it just adds a proper SMD header to the files. I've never liked uCon for file conversion and I suspect it is adding a bum header to your files. Is the 2nd byte of the file 0x01? |

As far as I remember neither Ucon64 nor GG2SMD generated proper headers for SMS games back when I messed around with my MD+ and SMS ROM Images years ago (could be wrong, though...). Here's what Charles McDonald's file format information says about the header:
| Code: | 2.) Z80 program files
---------------------
The SMD can accept Z80 programs, which are executed by the machine
in the Mark-III compatability mode. For some reason, these files only
work when loaded via floppy, as opposed to the parallel port. This
could be a limitation of the SMD's firmware or an issue with the
transfer utility, which may only expect to send 68000 programs.
The files consist of a 512-byte header, and then the raw Z80 program data.
Header format:
Byte 00h : Size of file in 16K blocks.
Byte 01h : 02h
The remainder of the header should be set to zero. |
I think I remember always adding AABB06h at offset 08h like in a proper SMD header. Really, a lot of games work, out of the top of my head it was mainly Phantasy Star and Ultima IV that bothered me most for not working. |

GG2MD does seem to work. I tested
Shinobi, Alex Kidd In Shinobi World, and ALF so far.
Shinobi needed to be reset before there was any sound
and the other two showed a blank green screen before resetting, but they all work fine once reset.
Only downside to playing SMS games like this is the lack of a pause button.
Also, I tried converting the BIOS files with GGMD and it just gives an error about the filesize so I guess those won't be possible. No biggie.
I'll update when I try more games.
