    I'm trying to create a 16:9 Patch for Solatorobo: Red the Hunter (U). However, the value 00001555 is found 15 times and changing them one by one doesn't alter screen size (at all!). I searched for 00005461 alternatively, but nothing appears. Can someone lend me a hand? What am I doing wrong, and what can I do to get this game working proper?

    @Hakaru You were on the right track, Solatorobo does use 1555, not 1548. I started looking at that game and decided to put it on the backburner because however it handles aspect ratio, it looked complicated as hell. I found different addresses which affected the title screen, cut scenes, different areas in the game, etc. I tried searching for a pointer (a place in memory which "points" at another place in memory, like a signpost that says "Aspect Ratio stuff is over here!"), but I didn't find one in the time I spent on the game and I eventually moved on. I do plan to give the game another look, but yeah, it's a tough one.

    I don't specifically remember if this was the case with Solatorobo, but most games don't show changes in aspect ratio immediately, you have to load a new area entirely or just reboot the game, so that may be why you weren't seeing any changes.

    That's some good news! Solatorobo really does deserve the HD treatment in 16:9. So glad that someone else took a look at it, even if it is on hold and a WIP. At the very least, you already found some cases where you could convert some certain elements to widescreen through 1555! I will definately wait patiently for you to revisit it, thanks!

    Is there any way to convert these codes to make them compatible with the Japanese versions of the games?

    Anyone know if it's possible to widescreen hack 2D Sprite games? In particular the entire DS Pokemon Mystery Dungeon series. (Blue Rescue Team--Explorers of Time/Darkness, Explorers of Sky). Thanks in advance.

    Hi, sorry if i didn't see it, but where's the download link for desmumar? I really really really swear that i didn't found anywhere here or in other place. Or i don't need it anymore, just regular desmume? Again, sorry to bother. Anyway, you did a really nice work here!

    I don't know what happened to it tbh. Here's my copy of DeSmuMAR.
    https://www28.zippyshare.com/v/0wdU00pI/file.html

    Perhaps you could release what you did find for Solatorobo in widescreen thus far? I found the address for the title screen, nothing else. Also, could you please, pleeease consider taking another look at this game? I've been working at it for two days now with no luck. If my assumptions are correct, no widescreen value for gameplay was found in all of the 1555s. Thank you thank you thank yooou!!!

    @Hakaru I've looked at the game on and off between other things and still haven't found anything very useful. There's not one address that covers a given location, e.g. the deck of the ship at the beginning of the game does not have "a widescreen address". It varies across resets, area transitions, etc. The title screen might be consistent because it's basically the first thing the game loads, so there's nothing else shuffling the memory layout around yet, but once you get in-game, all bets are off.

    From what I can tell, the maps themselves include the aspect ratio value, so when the game loads a new area off the cartridge into memory, that's where the address is placed. But the game doesn't load the maps into the same place every time, so unless a pointer is found to where the map is loaded (which I haven't been able to locate so far), there's really nothing anybody can do with that information.

    Without meaning to sound curt, nothing that I've found would be useful to anybody who knew what they were doing. I'm sure a more capable hacker than myself would be able to resolve this issue, but my information wouldn't be helpful to them beyond giving them the roughest idea of where in memory the game loads its levels. Regardless, here's a dump of any addresses I have written down:

    0x021CEF3C: Title Screen
    0x022A3F32: Ship's Deck (sometimes)
    0x022A3FD6: Ship's Deck (sometimes)
    0x022A3FE8: Ship's Deck (sometimes)
    0x022A3FEA: Ship's Deck (sometimes)
    0x022A1F2E: Inside the Ship (sometimes)
    0x022A1FD2: Inside the Ship (sometimes)
    0x022A1FAA: Inside the Ship (sometimes)
    0x022A21FA: Further Inside the Ship (sometimes)
    0x021E97E4: Medallion Cutscene (sometimes, probably, I only tested this far once)

    EDIT: OK, so we may possibly have some progress finally, on my ... tenth or so attempt looking at this game. Instead of tracing back where the aspect ratio data came from (which was a "dead end" since it came from the cartridge bus and that would mean just modifying the ROM), I followed it forward to where it ended up and patched it there instead, and it seems like, I will say cautiously, more than one map's aspect ratio ends up at the same place. I don't want to go and say "all maps" or anything crazy when I've only run around the ship at the very beginning. This code also widescreens the title screen and part of the intro cutscene.

    Code:

    EDIT4: Codes updated. Their behavior should be identical, but the new version uses slightly less code.

    EDIT5: Switched aspect ratio value to 0x1C72, per my reply below.

    After spending days delving through it, I couldn't figure out much at all. But, you've gone and finally figured it out! You just successfully modernized my favorite NDS game! You are now one of my favorite people!

    In the process of widescreening games, I've found that the way the games calculate 0x1555 is, simplifying somewhat, to do 0x1000 * 0x4 / 0x3. In decimal, that equals 5461.33333333, which you would round down to 5461, or 0x1555 in hex. Since there's already some rounding in the process of reaching 0x1555, this means any formula that aims to calculate a different aspect ratio based on 0x1555/5461 is introducing two levels of rounding errors, the original one to reach 0x1555 and a second one to reach whatever aspect ratio the user wants.

    So a more correct formula to reach the desired aspect ratio would be as follows:

    0x1000 * desired width / desired height

    Or, if your calculator can't do hex:

    4096 * desired width / desired height

    e.g. For 16:9, you would do 4096 * 16/9 = 7281.77778, which we would round up to 7282, or 0x1C72, rather than the currently used 0x1C71.

    For what it's worth: the difference this will make to the final picture is so fractionally small that it's almost certainly irrelevant to any possible uses.

    So I saw the instructions on how to find the codes for widescreen, and since I felt nostalgic for star wars the clone wars 3, thought I'd give it a try. However after trying each one of the codes I found that not one of them affected the game at all. I always considered the possibility that I was just doing something wrong, but I couldn't see where I'd messed up.

    The codes I got were:

    020F0C44
    021781B8
    021A61A4
    0226BB3E
    02294800
    022A4756
    023A34C4
    023A36B4

    Any help would be appreciated greatly.

    Hi,
    I'm not sure how it works.
    I have a monitor in 16:10 with a resolution of 1680x1050, what is the largest dimension that I can choose to play the NDS?

    I've been sniffing around for a potential solution to minimize the stretch on the 3ds widescreen feature in Twilight Menu for Soulsilver. I've noticed people have uploaded pictures of their soulsilver and it doesn't seem so stretched.
    My question is do these codes help that and if so how do I go about adding these codes

    Manually download it from the Artifacts tab of the latest build, and then rename it to DeSmuME.exe and place it next to DeSmuMAR.exe
