There is no shortage of attempts to make games from decades, past in today’s hardware, but there is at least one aspect that has not been able to adapt so far. These games were made specifically for the visualization technology of their period, which, mostly, referred to as aspects of 4: 3. Some purists may prefer to play classic retro games that way, but others would prefer not See the black borders around. Fortunately, a new MOD gives the SNES version of Super Mario World a wider window, whenever you are willing to go through the rings to work.
You really can not blame the developers of the past by not “future proof” your games. Nobody probably imagined televisions and monitors the aspects ratios of Ultrawide 21: 9 that some today still find ridiculous. Fortunately, developers can also get quite creative and ingenious, which leads to the modes that nobody would have believed possible, much less necessary, years.
This new MOD for Super Mario World works by modifying the internal play screen of 256 × 224 to 352 × 224 to obtain an aspect ratio of 16: 9. Of course, today there is no screen with that super low resolution density, So the other part of the formula requires applying other mods to support HD resolutions. That is why this particular mod until now works only with the BSNES-HD emulator and nothing else, at least for now.
However, it is not simple as downloading a rom and touching it in the emulator. You have to apply the mod to an existing ROM, which, for legal reasons, you have to get on your own. You also have to make sure you get the SNES version of Super Mario World, no, the most recent anticipated ports of the game or similar. There are other steps detailed on the SNE-SNES GITHUB page, but it should be simple enough for experienced emulator users to pass.
Some probably will disagree with playing the original super mario world on anything other than its original format 4: 3. This mod at least opens the doors for those who wish to take full advantage of the modern hardware. Supports 16: 9 and 16:10 monitors, but support 2: 1 and 21: 9 are also in progress. There is also a continuous interest in the development of a more generic “wide” mod that can be applied to any game of You have a ROM that exists somewhere on the web.
