NeoGeo CD optical drive replacement - SD card game loader
One Tuesday evening, Sasha sat hunched over his desk. Problem number five looked less like math and more like a secret code from an alien civilization. He scribbled, erased, and sighed, watching the clock tick toward dinner.
With the "map" to guide him, the rest of the problems felt less like a mountain and more like a series of stepping stones. Sasha finished his homework with time to spare for a game of catch with Rex. He realized that the textbook wasn't his enemy, and the GDZ wasn't a cheat code—it was the mentor he needed to help him speak the language of logic. gdz po matimatike dorofeev i peterson
"The GDZ isn't a magic wand, Sasha," she said gently. "It’s a map. When you’re lost in the woods, you don't just jump to the end of the trail; you look at the map to see where you took a wrong turn." One Tuesday evening, Sasha sat hunched over his desk
"Stuck again?" his older sister, Katya, asked as she leaned against the doorframe. With the "map" to guide him, the rest
In a small, sunlit classroom where the scent of old paper and chalk dust lingered, lived a boy named Sasha. Sasha loved many things—soccer, his dog Rex, and space travel—but he had a complicated relationship with his math textbook. It was the infamous edition, a book known for its challenging puzzles and multi-step logic.
"It’s this Peterson book," Sasha groaned. "It wants me to find the logic pattern, but I think the logic has gone on vacation."
"Oh!" Sasha exclaimed, his eyes widening. "I was trying to multiply before I simplified. The GDZ shows that the trick is in the grouping!"
The Neo CD SD Loader could be called an ODE (Optical Drive Emulator) because the benefits are similar, but technically speaking it isn't really one. It doesn't simulate an optical drive. It provides the console with a direct interface to an SD card and patches the BIOS to load games from it instead. From an user standpoint though, the functionality is the same !

Installation requires some soldering, but nothing too hard except one delicate part (see instructions). There's no need to cut the plastic shell of the console.
If ever needed, the whole kit can be cleanly removed and the console restored to its original form.
Yes, just like you could run them by burning CD-Rs. The loader doesn't circumvent any anti-piracy features since the NeoGeo CD doesn't really have any. However, some games implement copy-detection measures that may be triggered. Patched versions of the games do exist.
If you like indie games, please buy them :)
Yes. The original CD drive can be kept operational if needed but you will only be able to use microSD cards, not full-size ones.
No, except if a conversion exists. A few games have been converted by enthusiasts, but not all.
The loader can't automatically split a cartridge game to add in loading screens.
This is a very complex process which can't be done automatically.
No, however the loader's menu itself brings similar features such as cheats, region and DIP-switch settings.
The full NeoGeo CD library fits in a 64GB SD card. Speed (class) isn't important, any will do.
Installs on which the CD drive is kept in place only allow microSD cards.
Only SDSC, SDHC and SDXC cards are supported. WiFi-capable and other weird SDIO cards may work but are NOT tested.
Both can be updated by placing an update file on the SD card. Updates are provided for everyone and for free.
Yes. If you burn it to a CD and it works on an un-modded console, then it will work with the loader.
No guarantees that it'll work perfectly if you only tried it in an emulator. Making it work on the real console is up to you !
The firmware doesn't rely on a list of known games. It will load any CD image as long as its file structure matches the one required by the console's original BIOS. This means existing and future homebrew games can be loaded without having to update the firmware.
Using an ultra-fast luxury SD card won't improve loading times. The speed is limited by the console's memory. Even my oldest and slowest 128MB card currently isn't maxed out.
No. The devices may serve a similar purpose (replacing a storage medium with a more modern one) but the companies and people involved are different. The NeoCD SD Loader only works on CD systems.
No. I only keep an anonymous list of the serial numbers of the kits I built. This is used to keep track of which hardware version is each kit to make customer service easier.
Yes, see https://github.com/furrtek/NeoCDSDLoader. Be sure to read the rules !
