Vs. Super Mario Bros. - Home Edition -

Hack of Vs. Super Mario Bros.

Description:

This is a hack of Vs. Super Mario Bros. that allows the game to be run on a standard MMC1 cart with 8KB SRAM. No custom hardware required!

It also adds the following features:

  • Pre-game menu that allows you to set dipswitches and reset the high scores
  • High score retention (when using battery-backed SRAM)
  • Correct NES colors (Vs. hardware used RGB PPUs with scrambled colors)

This patch works with either of the commonly available Vs. Super Mario Bros. NES ROMs. It has been tested on the PowerPak, but should also work on any other flash cart or copier with basic MMC1 support.

Version 1.1a:

  • ROM header was erroneously set to NES 2.0 with incorrect SRAM size, causing some emulators (and maybe newer flash carts?) to not actually save SRAM. This has been corrected. (NOTE: PRG data remains unchanged, so dedicated MMC1 carts do not need to be updated.)

Version 1.1:

  • Fixed intermittent scanline glitch on NTSC PPUs (this affected the original game as well)
  • Changed default dipswitch settings to match those found in the operation manual; defaults can now be restored by pressing A + B + Select at the menu
  • Dipswitch settings are now saved in SRAM
  • Implemented timer speed settings for both original and alternate ROMs (no need for separate ROMs anymore)
  • Minor fixes and cleanups

Can't Play Without It

Reviewed By: PowerPanda on 13 Oct 2020

And I mean you literally can’t play without it. This patch is necessary in order to get the game to work on emulators and flashcarts. Being able to set the difficulty at the beginning via the dipswitches is great addition, and handled very well. The default settings for this game are just kind of cruel.

Version 1.1 Recommended - Yes
