Final Fantasy VII NES Demake (2026 Overhaul Updates)

DrgnMasterKota · 2026-07-12T08:48:15+00:00

This update project has been in the works solo development wise by me on and off for the last year with me completely reverse engineering and coding the game to implement many, many, many needed quality of life improvements to better get this NES Demake inline with the true source material of the original PS1 version. Currently this update goes all the way up to the Mr. Dolphin event in Junon with the Boss battle of Bottomswell. I just wanted to get a playable build out there in the wild for people to playtest and enjoy with the excitement for the updates to come which should be much faster now that I have decompiled all of the code base and understand what I'm working with. I also want to take this time to give full credit to the history work on this FF7 Demake. It started off as a NES Chinese game bootleg released by SHENZHEN NANJING. Then went on to become a massive 4 year long Rom Hacking passion project of Lugia2009 and his team of contributors Lindblum, Chpexo, FlamePurge, Dizzy9, Tsumai, Dr. Mario, Sirasu, keithisgood and Darkmew5. It's thanks to their hard work that we had the polished and happily praised V1.1 game update release that brought the original Chinese game bootleg up to standard. And now I'm doing the same myself as a solo dev to continue to improve the game beyond that standard with these 2026 updates. "This project sounds cool. But DrgnMaster what all does it really change and update?" I'm glad you asked, let me list a few examples. MAIN CHANGES FROM V1.1: - Adjusted the games encounter rate to feel more balanced and less overwhelming. (Yes no more getting into a battle every 3 steps) - Added new custom enemy encounter pools for specific story areas. (Each area now has it's respective enemies only, like the PS1 original, no more random enemies) - Improved enemy variety so different maps feel more distinct. - Increased battle run % chance from original 11% to a balanced 38% based on various level comparisons. - Preserved and improved key music/event cues while also restoring the 3 cut songs from the game "Trail of Blood", "JENOVA" and "Attack on Shinra". - Fixed various found text typos throughout the game. - Removed enemy encounter logic from any locations that shouldn't have it. That is just some of the many big improvements that I have been working on and done for the game. I'd love for this project to inspire other devs to want and contribute to this project further, potentially leading to more massive improvements or additions like adding Yuffie and Vincent into the game or even expanding the story out to fill in some of the missing jumped gaps from the original game. Download the latest update for the project here: How to Apply the Final Fantasy VII Demake V1.2 Patch This is an update patch for Lugia2009’s completed Final Fantasy VII Demake V1.1.

Lugia2009’s V1.1 patch must be applied first.

Hi guys,

I have one of these Retroscaler BlueRetro adapters for my N64.
https://ae01.alicdn.com/kf/Se7ccbda...le-to-PS3-PS4-PS5-8bitdo-Switch-Pro.jpg_.webp

The FW is: https://github.com/RetroScaler/N64-Blueretro/releases/tag/v24.04

I can format/read/write mpk memory data at all memory banks with the help of the web GUI, but my N64 says it can not read from the virtual memory pack. When I attach a real memory pack to port 2, this one works fine, but not the virtual one.

I can also switch between rumble and memory with the home button and the N64 recognize the difference. But in memory mode it seems corrupt.
Games with built in memory pack manager can detect the broken virtual pack and offer to repair/format it. But also this method fails.
I don´t have further modification at this N64 that could interfere.

I tried to write a preformated mpk file from darthcloud, but it does not change anything.
I had different FWs versions.
I used the Altra64 format instead of the web GUI or ingame functionality. No change.
I changed the memory bank and also the output port.

The funny thing is, I just sold another N64 where I integrated an ESP32 and here the memory pack worked perfect.

If anyone has any ideas, please let me know. Otherwise, the only option for now is to use a physical pack.

THANKS

update:
i have now probably found the reason. if i connect more ports, the n64 recognizes the virtual memory pack. however, if i also assign memory packs to the other controllers, problems occur again. then usually only one random pack works and the others are not recognized at all, or switch themselves on and off every second. however, one pack is enough, so i have deactivated the other memory packs and it works satisfactorily.
