Thank you everyone for the kind words!
I've noticed some people are having to navigate patching for the very first time due to v2.00; since mziab and I will keep support for v2.00 as future revisions release as necessary, I've made a guide.
How to Patch Sailor Moon: Another Story in English
1. Get a Japanese ROM
of Bishoujo Senshi Sailor Moon: Another Story.
The unofficial SMAS localization team cannot help you find this. Your best bet is to use your search engine of choice. No parties involved in this fan project accept liability for damage incurred to the end-user, their OS, their hardware, etc. while downloading from ROM-hosting sites. However, please note that your browser should be able to catch any issues prior to downloading; adding to that, always ensure you scan a file with your antivirus program before you un-ZIP it.
Please hold onto your Japanese original ROM, as you'll need it to apply any future revisions.
2. Use ROMhacking.net's online ROM patcher. https://www.romhacking.net/patch/
This can be used on any OS. Where it says "ROM file:", click the "Choose File" button. Navigate to your Sailor Moon: Another Story Japanese ROM. The patcher will detect if there is a header or not. Headers were once necessary for copiers, or devices that would let you play ROMs on a real SNES before modern conveniences were made available. We want there to be no header
to patch Another Story.
If the patcher displays this:
Great, move on. You don't need to do anything else.
However, if this is shown instead:
Tick the box next to "Remove header before patching:". If there is a header on your ROM prior to patching it, the game won't load.
At the "Patch file:" section, click the "Choose File" button down here and navigate to the translation patch. The revision number will change as newer builds come out, but it will always say "PSSMAS_T-Eng" in its name.
Finally, click the colored "Apply patch" button in the lower right, and your patched ROM will download.
2a. Possibly repeat the process for the Grind-Be-Gone
improvement, if you wish to use it. Using the directions above, substitute the Japanese original ROM for the English-patched one, as well as the translation patch for "PSSMAS_Grind-Be-Gone_v100.IPS".
3. Load the file into your emulator of choice.
Emulation is easy once you get the hang of it, but I won't be covering that in this guide. Please refer to FantasyAnime's "Emulation for Newbies" tutorials for more information.
