Hello! I've been playing this game for over 20 years, returning every year or so to play. I've done some speedrunning of it as well (via 15 card mod) and had a blast. I'm hoping the community can come together to assist in transforming this game in ways we've never seen.

Forbidden Memories has been statically recompiled: the PS1 MIPS code is translated to C ahead of time and compiled into a native Windows executable. It isn't an emulator, the game runs as a program on your CPU.

It's built on PSXRecomp by mstan, which does all the heavy lifting. What I added is the game-specific side.

You bring your own disc. The download contains no game code and no game assets — not the executable, not the sprites, not even the font. On first run it asks for your disc image, translates the game from your copy, and compiles it locally. That takes a few minutes and happens once; every later launch starts immediately.

What I added — all in an in-game overlay menu on F10, applying immediately:

• Duel rank meter. The game grades every duel you win but only tells you afterwards. This puts the grade on screen during the duel, drawn with the game's own POW/TEC badge and rank letters, beside the FIELD box. Optional raw 0–99 score, or a plain-text corner mode nothing can cover.
• Fusion assistant. The game has thousands of fusions and teaches you none of them. This reads the cards actually in your hand, checks them against the game's own fusion tables in memory, and marks the pick order — optionally naming the card it makes. Optimises for attack or defence.
• Card drops. Stock, a won duel awards exactly one card. This makes it 1–99, and adds a results screen the original never had: three pages of what you won, with the game's own yellow "New!" tag on anything you didn't already own.
• Cheats. Life points, starchips, free spending, fill-the-trunk.

Plus what the framework brings: save states, rewind, a speed multiplier, and a fast-loading option that cuts disc loads to near-instant (off by default).

Before you try it:

• Windows x64 only for now. The framework supports more; I've only built and tested this.
• USA disc, SLUS-01411. PAL, Japanese and Greatest Hits discs are different programs — the build refuses them by CRC and says what it expected.
• You need Python 3. The first run downloads a compiler if you don't have one.
• The first run takes a few minutes and a console window will sit there working. That's it compiling the game, not hanging.
• It's a 0.1.0 — tested cold from a fresh install, but it hasn't had many eyes on it.

The game builds the first time as I took care not to release any Konami code or assets so they must be pulled from your own disc.

Fusion Helper: Toggle between OFF, NUMBER ONLY and NUMBER AND CARD INFO. Choose between sorting by the highest attack or defense fusion. The card name will highlight in green when you have the correct order of cards that end in the helper's target.

1-99 Card Drops: This is a built-in MOD that can be toggled. CPUs now drop 1-99 cards and the value can be changed at any point during gameplay. The results pages have been modified and will generate a list of all cards earned during that duel. The deck menu will tag all new cards, up from the previous limit of 16.

Looking to release on GitHub with source code within a couple weeks. In my experience it is stable from start to finish. At this point I'll be shifting my focus from adding features to cleanup and organization. Looking forward to seeing how this will be expanded upon by the community.

Hello! I've been playing this game now for over two decades and I'm not sure it'll ever stop. I come back to it at least once every year and try to come up with a new fun way to play it. I used to speed run it under category extensions (15 card) and had a blast. Looking to release this project within the next 30 days. Looking for suggestions if you have any.

Hello everyone! As many of you may have noticed, we were under attack. My account was compromised, i hope no one of you fell for the scam attempts over the weekend!

The issue is now resolved my account has been recovered and safer than ever. I am incredible sorry this has happened, i downloaded a malicious chrome extension which lead to the attackers overtaking this sub.

Thankfully due to reddits friendly and competent admin team, the issue was resolved as soon as they could after the weekend.

Thank you to anyone who sticks arround and participates in the community, and again an apoligy from me! I didn't take reddit account security serious enough and was proven that even people who do otherwise good cybersecurity practises, can be infected. Stay safe!

Every Forbidden Memories mod eventually sends me through the same routine:

1. Alt-tab to a fusion spreadsheet

2. Search the current opponent’s drop list

3. Check which rank can drop the card I want

4. Return to the duel and try to remember everything

So I built YGOverlay, a Windows overlay that puts those answers next to the game.

What already works in the current build:

• Live Fusions: reads your current hand and updates the available fusion options as it changes

• Farm tab: detects your current opponent during the duel

• Rank projection: shows your projected rank and score, then highlights the relevant S/A-TEC, B/C/D or S/A-POW pool

• Drop tables: shows every possible card, its drop chance and card type in an alphabetical list

• Trunk tracking: shows how many copies of each card you currently have in your chest

• Planning mode: lets you manually select a duelist before starting the farm

• Mod-aware data: uses the fusion and drop tables from the selected or imported PS1 mod, including support for The Last Memories’ drop format

The fusion assistant works with PS1/ePSXe and Forbidden Legacy. The Farm tab is currently available only for PS1/ePSXe.

The rank projection is still marked as beta while I finish validating every scoring counter in live gameplay.

This isn’t a sales post, and access isn’t open yet. I want blunt feedback from people who actually play and farm Forbidden Memories.

Would this replace the spreadsheets you currently use?

If so, comment with the mod + opponent you farm most. I’ll use the most requested combination for the next gameplay demo.

Has anyone been able to get ePSXe running on Steamdeck to play FMR romhacks? And if so, do you have any setup tips and tricks?

The PS1 emulator that comes standard with Emudeck (Duckstation) is unfortunately not compatible with most FMR romhacks in my experience.

I've also seen someone attempt an installation guide but I have not been able to replicate their success: https://www.reddit.com/r/SteamDeck/s/oSZPMI8mcw
