I updated the cartridge firmware to take advantage of DMA when transferring data to the Saturn. When uploading to workram-L, the speed increased from about 320KB/s to 430KB/s, and when uploading to workram-H the speed increased from about 370KB/s to 590KB/s. I also added a "run" command to the ftx tool, which calls the specified address without having to upload anything. The code is available on GitHub.... | ||||

An update nearly 3 years after initial release oO Thank you antime ! USB dev cart is now something like 25 times faster than Action Replay !  | ||||||

| I was bored... In practice the difference isn't really noticeable, since the uploaded files are so small. | ||||

Yes, it's something like filling both hram and lram takes something like 5 seconds instead of 6 seconds ... but...  Edit : I prepared your new firmware for my USB dev cart  I plan to use it next week or so. | ||||||

| What is the licensing on the ftx tool? | ||||
|
antime | Sep 13, 2015 | ||
| 2-clause BSD (the license text is the first thing in the source file). | ||||

Ow, how embarrassing. I have that habit of looking for the LICENSE file and not looking at the source files. Thanks. | ||||

Using FT D2XX library, would there be any reason as to why reading intermittently blocks despite setting the RX timeout to a low value? I set the USB in/out payloads to the same values as in antime's tool. Any guesses? | ||||

| just dumb question, what's the way to get game saves with the usb dev cart ? i did that with old tool and my isa card and maybe it was possible with the usb data link. | ||||

From command line : USB Data Link : SatLink.exe usb_data_link.ini -bs test.bin USB dev cart : SatLink.exe usb_dev_cart.ini -bs test.bin From GUI : Select which device to open (USB Data Link or USB dev cart) in tool bar -> "Open" menu, then click "Receive Backup Memory" in tool bar -> "Receive" menu. | ||||

nice but is there something better ? i mean you choose the game save you want to get | ||||||
|
cafe-alpha | Mar 16, 2016 | ||||
Something like in yabause's save manager ? No, sorry. The only way to do this is to use both SatLink and ss-save-parser tools ... I can add such feature to SatLink, but I would like to know how many people are interested in such feature before coding it. | ||||||

Hi all, Just posting that I've been working on a case for cafe-alpha's USB dev cart. This was specifically made for version 3.2 of the USB Dev Cart but it also works for revision 2f and probably other revisions. Here's some pictures:     I will be posting on thingiverse at some point. Enjoys. ^_^ | ||||

Some people may wonder why the case has such weird "square" shape : it's because the PCB for my "USB & Gamer's Cartridge"... is larger than other cartridges : 100mm x 100mm, vs 100mm x 77mm usually. I plan to re-design the PCB for "USB & Gamer's Cartridge" so that it can fit in Action Replay case. Priority for this re-design job is relatively low, but this will be done someday | ||||

While your doing all this 3d printing, do you think you could do me a huge favor and 3d print me a 3d printer so I can join in on the fun? XD. If only it worked that way hahaha, keep up the awesome work though! | ||||||
