The "Booting CD ... Error 1" message.
Special Thanks to C.L. for reporting the problem and sending the picture
This problem happens with Pseudo Saturn 0.832, both "no logo" initial build and final release with classy logo.
It concerns :
- A specific hardware revision of Saturn : Japanese grey model 1 (95% sure), with power supply connector screwed to Saturn top case (not so sure).
- Any game or application on burned on CD-R
So if you have Pseudo Saturn 0.832 and the "wrong" (incompatible) hardware revision of Saturn, it's not possible to play any CD-R copy of your games, and consequently can't upgrade your cartridge to other version of Pseudo Saturn, since it requires to boot a CD-R

Annoying isn't it ? The countermeasure is to either :
1. Install
latest Pseudo Saturn Kai on your Saturn cartridge
2. Use another Saturn, compatible with Pseudo Saturn 0.832 :
- Model 2 Saturns are 99% safe : I didn't received any "Boot Error 1" report with model 2 Saturn.
- Please try on another model 1 Saturn only if you were lucky that day, else please be sure that this other Saturn won't be compatible too

Owning a spare and compatible Saturn -or being friend with somebody owning one- is the best solution, since it allows to both upgrade to Pseudo Saturn Kai, and to play games compatible with "JHL (PS 0.832)" game loader.
Owning only 0.832 incompatible Saturn(s) will bring you to "install Pseudo Saturn Kai on a bare Saturn" step, so basically requires to open your Saturn, watch
swap trick tutorials on youtube, fail several times in trying that ('%)=(&$ swap trick, finally success in installing Pseudo Saturn Kai

, look for one missing screw in order to put back Saturn top cover, re-open the Saturn in order to remove the tape on CD-ROM lid open switch, and finally put back the Saturn in its original condition

Long install steps ? Yes, but at the end the problem will be fixed

(if not, please
contact me)
However, there's a limitation when using Pseudo Saturn Kai on model 1 incompatible Saturns : the few games not compatible with Pseudo Saturn 0.831 won't be playable

Incompatible games are the ones marked as requiring Pseudo Saturn patcher utility, in
Pseudo Saturn Kai compatibility list. Notable examples are Panzer Dragoon Saga, Batman Forever and Alien Trilogy.
You sold a kidney in order to buy original discs of Panzer Dragoon Saga, and really want to play their CD-R copies on your model 1 Japanese Saturn so that original discs won't be damaged ?
Except selling the remaining kidney in order to buy a Rhea/Phoebe (

), the only solution is to wait until a new version of Pseudo Saturn Kai is released, and hope I find a fix to this problem.
While waiting for new version of Pseudo Saturn Kai, how about trying games that Pseudo Saturn Kai can play with its good old "CWX (PS 0.831)" game loader ? I would for example recommend NiGHTS into dreams, Shining Force 3 series, and also Virtua Fighter Kids

"
Firmware file read error !" message when trying to install Pseudo Saturn Kai

"Firmware file read error !" message (hard to read, sorry).
Grabbed from
reddit, special thanks to
yoqu for reporting the problem

First, I fixed error text display in Pseudo Saturn Kai's latest release
(v6.074) : it is now displayed with white background color. Readability
varies from a TV monitor to another, so please
contact me if that's
still not readable on your TV

This problem is generally caused by incorrect timing when performing swap trick, which makes Saturn booting Save Data Manager and Flasher utility from CD-R, but not being able to read files from CD-R after that.
Another causes may be Saturn's laser incorrect calibration, or affinity problem between Saturn CD block and CD-R brand, or burn settings.
The countermeasure is simple : please use Pseudo Saturn Kai alternate flasher utility, located in
Pseudo Saturn Kai latest archive → pskai_alternate_flasher.iso. This requires another CD-R, but this will work

And, burning Pseudo Saturn Kai Save Data Manager and Flasher utility (pskai_sdm_flasher.iso) wasn't a waste, since it will boot correctly after flashing your cartridge to Pseudo Saturn Kai. Save Data Manager contains many save data to import to your Saturn, so you probably want to use them in order to start playing your favorite game elsewhere than level 1

So, what's the magic behind Pseudo Saturn Kai alternate flasher utility ? nothing really special in fact : both flasher executable and Pseudo Saturn Kai firmware data are packed in a single Saturn executable file. So as firmware data is loaded just after performing swap trick, file read error won't happen

Definitely not a smart way to counter a problem,
but it works, which is the most important 
This "alternate" flasher utility was developed before Pseudo Saturn Kai, and used in Pseudo Saturn 0.83x flasher utilities. I then developed an "all in one" Save Data Manager & Flasher utility on a single CD-ROM which allows to flash cartridge, manage save data, etc.
I though this would make the "alternate" initial flasher utility obsolete, so that it was dropped in Pseudo Saturn Kai 6.036 and 6.037 releases ... unfortunately I was reported about that "Firmware file read error !" problem after that

So as a countermeasure, I restored this utility from Pseudo Saturn 6.074. Sorry for the troubles caused

Additionally, some more informations about this problem are displayed in current (W.I.P.) Pseudo Saturn Kai version.
Updated error message in flasher utility.Pseudo Saturn Kai development continues ! Stay tuned
