Winter 2022/2023 AVS update! This update applies to ALL orders for the AVS. See pinned posts on our twitter or
for full details.
Play your NES games with just one cart!
The NES flash cart is finally here and it couldn't be easier. Just copy your games onto one compact flash card, insert into the PowerPak, and play!
When you start your NES you get a file browser to choose your game. Then you can save and load battery ram so all your saved games stay saved. Save files can also be transferred to and from your computer for use on emulators. Built in Game Genie code support lets you use cheat codes. Even better than the original Game Genie, the PowerPak has support for 5 codes at once.
Games load very fast, average around 7 seconds. This means a quick cycle for homebrew development on any mapper. Now you can see your game on real hardware instead of relying on emulators. FAT16 or FAT32 format is used so there is no special software to load games onto the card. Organize your games in folders any way you want for faster browsing. Compact Flash is used instead of something else like SD for maximum speed. The NES processor is the bottleneck so the parallel CF card is more than 10 times faster than the serial SD card.
The entire PowerPak system is updateable for future additions and bug fixes. All mapper files are stored on the CF card for easy upgrading. Just download the most recent Mappers file below, unzip, then copy the folder to the root of your CF card. Using CopyNES the boot rom can be reflashed but this will hopefully never be needed. If it is needed and you do not have a CopyNES, you just pay the shipping to get your PowerPak here and I will reflash then mail it back free.

CF Card Reader
CF card and reader are not included!
What type of CF card do you need?
1,000 NES games takes up approximately 200MB, so any size between 256MB and 32GB will work and be enough space. Larger sized cards may have issues. CF card transfer speed should be 133x (20MB/s), faster cards may have issues.
CF cards listed as "high speed" or specific for high end digital cameras
may not work.
CF cards with built in wifi
will not work.

Mapper Compatibility List:
Current Known Bugs:
PAL compatibility has not been fully tested, only that it will run games.
MMC5 support not implemented yet. The PowerPak DOES have enough hardware to do it.
There may still be some sprite related graphics glitches on some NES systems.
Current Known Bugs that aren't Bugs:
File display does NOT sort alphabetically. Sorting would just be too slow for the NES processor.
Some emulators (Nestopia) use .sav files that are actually .zip files. These will need to be expanded before transferring.
DIP switches in arcade games will not work. They are not physically possible from the cart side.
Any game with PRG or CHR larger than 512KB will not work. Most are listed as Bad Mappers above.
Only the first logical partition on the CF card is used.
