USB dev cart #anchor#

USB dev cart is a cartridge that plugs into Saturn cartridge port and allow USB-based fast data transfer between your Saturn and PC.
Main purpose of this cartridge is to upload binary/executable data to your Saturn, easing the development of homebrew applications on Saturn.
Note: I have not designed this cart from zero by myself. It is the result of antime's work.

Saturn Gamer's Cartridge #new# #anchor#

Codename : "SD MemCart" : this cartridge features a SD card interface and emulates backup memory cartridge behavior on SD card.
Fed up of limited memory size of your official memory cartridge ? Me too #smile#
Fed up of not being able to share your favorite Saturn RPG saves via internet to your gaming friends ? Me too #smile#

Gamer's Cartridge main features :

- Play import games. (*1)
- Play CD-R copy of your favorite games. (*2)
- Memory cartridge on SD card. (*2)
- Dump Saturn internal backup memory to SD card.
- Play small homebrew programs from SD card.

(*1) Bypass game region protection, so some games optimized for NTSC may not work well on PAL systems, and vice-versa.
(*2) Direct (in-game) save access, with relatively good game compatibility. Please check Pseudo Saturn Kai compatibility list for details.

IMPORTANT : Gamer's Cartridge is not an Optical Drive Emulator (ODE) and consequently doesn't plays commercial games from SD card.
Please take a look here or here or here or here if you are looking for an ODE for your favorite game console.

I plan to add few more features in cartridge's firmware (upgradeable on user side). Please check my blog from time to time in order to be informed about latest features additions #smile#

Order form for international orders is currently unavailable.
It will be back soon after processing current orders.

Gamer's Cartridge Gamer's Cartridge Gamer's Cartridge Gamer's Cartridge Gamer's Cartridge Gamer's Cartridge Gamer's Cartridge

Pre-order, pre-payment and anything else involving money aren't accepted while preparation of cartridges isn't terminated.
So if you went here to order a cartridge, please patiently wait for this page to be updated : this usually takes few days until returning back to available status.

How to wait until this page is updated ?

The best solution would be me to put a mailing list system here which would inform persons registered there at the right moment ... but homepage provider sometimes neglects to send email (hosting costs are from my pocket money, so no, I won't pay for something more performant) so this is not a reliable solution.

A laborious solution would be you to refresh this page frenetically, but I hope you have other things more interesting to do #smile#

So I would recommend to use a solution which emails you back when this page is updated, such as Visualping #smile#
This does the frenetical page refresh and update check for you, and shall email you at the right time when cartridges are available.

Note/disclaimer: I'm not affiliated with (nor receiving advertsement money from) Visualping, so can't be held responsible if you missed Saturn cartridge order, or your bus to school/work, or the opportunity of your life, or anything else !

Cartridge Order Flow #anchor#

How ordering a cartridge works :

1. Patiently wait until cartridge order flow is available above.

By default, Pseudo Saturn Kai is installed in your cartridge.
It's possible to upgrade cartridge firmware on your side. Please do it at your own risks.
I'm not responsible of any damage caused by firmware upgrade !

(Common sense) rules around ordering process :

- I wait for payment for two (2, 1.414…2) days. If payment is not received after this delay, cartridge is put back for sale.
- I'm not a machine, so salutation words ("Hi", "Regards", etc) in your message are always appreciated #smile#
- Don't. Send. Many. Emails. At. Once. Grouping all your messages in a single one is better #magic#

Disclaimer #anchor#

Gamer's Cartridge is "just" a XL-sized memory cartridge using SD card which also plays CD-R games : it is not an Optical Drive Emulator (ODE) and consequently doesn't plays commercial games from SD card. Please take a look here or here or here or here if you are interested in such kind of device.

Gamer's Cartridge doesn't feature extra RAM, so the few games requiring it (Metal Slug, and several fighting games. Complete list available on satakore.com) aren't compatible with Gamer's Cartridge.

Gamer's Cartridge doesn't support of ODEs other than Rhea/Phoebe or Fenrir is not guaranteed. So for example in the case of Terraonion MODE, cartridge backup access may not work.

Cartridges are hand-made : electronic components are hand-soldered, holes for LEDs and SD card socket are drilled and filed by hand, labels are printed, cut and sticked by hand, etc. So please don't order cartridge here if you're expecting to get something made at professional quality.

The cartridge may sometimes not boot to Pseudo Saturn Kai menu. This is usually caused by an improper connection in Saturn cartridge slot and is fixed by adjusting position of the cartridge.

(Same disclaimer as above, translated in Japanese)
・Gamer's Cartridgeでは拡張ラムが搭載されていませんので拡張ラムを使用するゲーム(SNKゲームなど、一覧表はこちら)は非対応です。
・サターン本体との相性によって、カートリッジからPseudo Saturn Kai画面へ起動しない場合があります。

FAQ #anchor#

Q: What is the difference between Gamer's Cartridge and USB dev cart ?
A: USB dev cart allows fast USB transfer between Saturn and PC and also plays CD-R games : it's useful for Saturn homebrew software developers, not very useful for other people.
Gamer's Cartridge is a XL-sized memory cartridge using SD card which also plays CD-R games.
If you want to have fun in playing Saturn games (especially the ones using backup memory cartridge such as RPGs, Dezaemon 2, etc.), then Gamer's Cartridge is the best choice for you.
If want to play Saturn games, and occasionally make some small homebrew programs, Gamer's Cartridge choice is still OK since it allows to execute homebrew programs from SD card.
If you want to do intensive Saturn game/application development, with large programs and data files, gdb usage, etc, then you may prefer USB dev cart.

Q: Can I play official/backup Saturn games when using the USB dev cart ?
A: Yes, Pseudo Saturn Kai allows this.

Q: My cartridge doesn't works !
A: Please contact me in order to describe precisely what's wrong with your cartridge.
If your cart can be repaired, all the shipping fees, as well as the money needed to purchase replacement ICs are at your charge.
(Note : each cartridges are tested before shipping.)

Q: Can you discount your carts ?
Q: PCB costs x $ from that manufacturer, ICs cost y $ from that seller, so how about selling your cart at x + y $ ?
A: Short answer : I. don't. discount.
Detailed answer : x + y is parts/material costs. You forgot to add the following items in cartridge cost :

- Shipping costs from PCB manufacturer and ICs salers.
- Risks taken when producing several carts at once (if I make 10 PCBs and sell only 3, what should I do with the remaining 7 ones ?)
- Time taken to solder ICs, to flash firmware(s), to test cartridge.
- Tools and consumables items cost : soldering flux, tin, soldering iron, etc, etc.
- Time spent in designing this homepage, costs for hosting it.
- Time spent in desigining cartridge PCBs.
- Time spent in developing cartridge firmware.

I probably forgot a lot, but I hope you understood : cartridges are developped, assembled, tested and supported on my free time. I don't plan to pay my loans from selling Saturn cartridges : I have a regular job for this.
I set cartridge price to something reasonable for an homebrew item, and hope to sell enough carts in order to pay current cartridge prototyping costs. If I charged everything listed above, I doubt cartridge individual price would even fit in a 3 digits USD price.
Maybe your culture is tolerant regarding price discount. I personally hate price discount.

Q: I want to make a custom cartridge ! Are you ready to listen to my requirements and specifications ?
A: NO. Because I do Saturn things for fun during my spare time.

Q: Where are the tools in order to use USB dev cart under Linux ?
A: There are several tools available for linux users :

- ssload tool from libyaul, by mrkotfw.
- Saturn USB dev tool, by Razor85.
- ftx utility, by antime.

Note #1: Each tools have their own pros and cons, so please select by yourself the most suitable tools for your needs.
Note #2: Before shipping, USB dev carts are tested under Windows. I don't guarantee them to work on Linux.

Q: When using Gamer's Cartridge, does using an extra large SD card will provide more free room for memory cartridge ?
A: No : this won't change anything, so using a reasonably sized SD card is OK #smile#
The reason about this limitation is that showing SD card whole capacity to games may cause compatibility issues regarding digits to display, or when calculating free remaining size, etc. As a countermeasure, Gamer's Cartridge is shown with contents similar to official memory cartridge, but with enough remaining space to make all games happy when verifying if cartridge have enough free room to store their saves.

Q: Does Gamer's Cartridge have limitation regarding saves count or size or anything else ?
A: As long as there is free space on SD card, enough remaining size in backup memory cartridge is show to game, so in the facts, size limitation shouldn't cause problems.
On the other side, save data count is limited to 400. This is inherent to Gamer's Cartridge implementation and is set to this value in order to avoid performance degration when accessing memory cartridge.
Please note however that it is possible to archive save data with Save Data Dump feature, which isn't affected with this count limitation. So this limitation should not be a problem for a normal usage of Gamer's Cartridge.

Q: Is there a FAQ regarding Pseudo Saturn Kai ?
A: Yes, it is available on its own page.
