| Yeah, I was thinking about something a few nights ago. I SDWTLC is really HiROM, then likely, what I think FuSoYa did was disassemble the ROM into 32K chunks after finishing his editing, then reassemble them with blank 32K chunks in between.
In other words, SDWTLC is Basically a LoROM game with blank bits of padding to make it work as a HiROM. Now, I can't prove or disprove this on my own, but can anyone else do so? I think that is a viable possibility because if DWTLC uses a full HiROM bank, then FuSoYa would have had to trace every offset, every single pointer, every sprite, and basically every byte in SMW and make sure everything was pointed correctly. Even for Fu, I think that would have been nigh impossible, so what are your guy's opinions on my hypothesis? |

| Best way to test this is to take the SDWTLC ROM, break it into 32K chunks, and then put together every other 32K chunk to make it back into LoROM. | |||

| I think you are exactly right, seeing as I discovered this myself a few weeks back. So my question is, if one was to delete the spaces in the ROM, would that make it once-again a LoROM? | |||

| Can i just clarify this so i understand it, so basically, when he made the rom he threw a load mroe blank stuff into the rom to make it no longer openable in lunar magic, so if that extra was removed it would now be a bogstandard mario rom which would be able to be ran in llunar magic once unlocked?
*just doesnt understand what hirom and lorom mean  |

| I can't test this theory, I don't have the stuff I need for it.
Xeruss, I think you could, so long as you changed the config byte for the ROM that controls Hi/LoROM seetings to LoROM. Try it, perhaps DWTLC isn't even locked! Kristopher: Yeah, something along those lines. |

| Well if you get it into a LoROM and LM still says it's locked, *wink* | |||

| Actually, FuSoYa moved sections of the game into the HiRom area (starts as 4F0000). That way he would have to do little, if any JSL modifying.
What he did do though was remove the STAR tags so you cannot find his custom data. It's there, but it's a total BITCH to find! 
Compare JSLs of the original SMW rom to that of DM. (edited by spel werdz rite + on 02-10-06 12:32 AM) |

| So... Fu did make it essentially a LoROM, but stored custom ASM in the HiROM parts? Meh- just disassemble the ROM into chunks, then look though the HiROM parts for the code, then search for it in an unmodified DWTLC ROM, then look for a JSL to the area by placing an execution breakpoint on the code in Geiger's SNES9X debugger.
Then, convert DWTLC to LoROM, copy over the code, RATS it, and re-point the JSL(s) as needed. |
