I finally had time to use my Saturn, and I could verify that iso/cue "loader" works on real hardware !
Of course it works well when reading from RomFs, and it works also well when reading file from SD card 
My test environment ... sorry for the mess 
(Micro SD card is located on top-left of the cartridge)
I lost some time to understand why data transfer from SD card was slower than expected, but finally understand why : some debug/whatever delay routine was called when accessing cartridge registers ...
Just putting some #if 0 around this delay code solved the "problem" ^^;

Second (and I hope last) part of this article ...
Last week, I spend half a day in getting rid of spam messages via my homepage contact form.
And, it seems to work well 
So today, I spent another half a day in getting rid of spam messages via this blog's comments 
So I removed bullshit advertisement messages scattered on my blogs comments, and tried captcha plugin for PluXml (= my blog's CMS).
And unfortunately, image based captcha plugin doesn't seem to work well, because it blocks ALL comments ... very efficient spam filter 
So I added a simple additional test when posting comments. Hope you will solve it ... or not in the case you are a robot 
Extra : I spend the other half a day in testing Saturn cartridge with custom USB dev cart connected to my laptop and Open Logic Sniffer and JTAG (ByteBlaster on my desktop's Parallel Port, because I don't have enough budget to buy a USB Blaster ^^; ) around my Saturn 
Here is a snapshot of signals when it finally worked :
Can you guess what it is about ?
