To find the right hex addresses in Super Metroid, I need to find a LoROM hacking tool.Go back to your childhood with these retro sprites - inspired by (possibly) the best Mario game Super Mario World. Super Mario World and Super Metroid are even more different from each other than I thought, since even their cartridges work differently. In conclusion, the key search might have been a red herring it would have been too easy i suppose. This seems like a dead end to me though, so I will leave it for now. The key is supposed to have the address 0x80, which is not the case here (or at least it is not clear). Figure 7 – Lunar Magic options Figure 8 – YY-CHR, all SMW graphics The key can also be found faster, as shown in Figure 8. … Later I found that I made a mistake there is an option that does not split up the graphics, as shown in Figure 7. Figure 5 – Super Mario World graphics in YY-CHR Figure 6 – The key in YY-CHR After looking thourgh some of them, I found the key, as shown in Figure 6. Another problem is that the graphics are actually split up into 52 smaller files. This only serves editing purposes though and thus is not important for this project. The colors may seem off the reason for that is because the colors depend on palettes. The extracted graphic files can be opened by YY-CHR, as shown in Figure 5. However, hope is not yet lost – there is another useful feature: Extracting the graphics of the ROM, as shown in Figure 4. Lunar Magic only works for Super Mario World after all, unfortunately. So finding the key this way kinda does not count because the solution cannot be applied to Super Metroid. Figure 3 – Lunar Magic, Add Sprites Figure 4 – Lunar Magic, Extract Graphics It just took a few seconds to find what I looked for, as shown in Figure 3. Most importantly, it offers a very useful feature – adding sprites directly into the level. It is a level editor created by FuSoYa that was the only tool in this field for 18 years. Lunar magic is probably the best tool created for Super Mario World. This is where Lunar Magic joins the frey. How is it possible to edit Super Mario World Graphics, then? This might be the main reason why YY-CHR behaves the way it does. However, it is important to know that Super Mario World qualifies as a HiROM game while Super Metroid qualifies as LoROM. The topic is very technical and going into it further would be too much. Just a single byte in the ROM header indicates whether it is a LoROM or a HiROM cartridge – and that is basically it the SNES may read the data more efficiently when the byte is set to HiROM, leading to lower file sizes. The main difference between LoROM and HiROM is their way of handling memory (or, more precisely, memory mapping). There are two main types of SNES cartridges, the SNES community refers to them as LoROM and HiROM cartridges. The answer lies in the cartridges of the games. The results were sadly identical, as shown in Figure 2. So I tried the tool „Tile Editor“, which is a similar graphics editing tool that serves the same purpose as YY-CHR. Not a single graphic is recognizable throughout the whole pointer table.Įven trying to change the format and pattern did not help.įigure 2 – Super Mario World in Tile Editor The first question I asked when I approached the task of finding the key was:Īs shown in Figure 1, the program fails to identify the sprites of Super Mario World. In this blog, I will explain the differences between HiROM and LoROM SNES cartridges and I will go over some more tools used for hacking ROMs, specifically Super Mario World. I am certain that this key will unlock the next door to the spritelist. More precisely, I will try to find the ‚Key‘ sprite, that has the position 0x80 in the pointer table. To find an answer, I try to reverse-engineer MarI/O and take a look on how the sprite addresses were determined there. However, it is still unclear how to get the exact hexadecimal address of each sprite. Last week I found a tool that can be used to edit the graphics of SNES ROMs.
