Unfortunately, still no luck here. I took the latest version of Decrypt9WIP (20160118), placed the .dat in SD root, left the Decrypt9 entry alone (other than uncommenting the lines). Still a black screen on a 2DS with Menuhax 2.1 and SysNAND 9.2.

;From here on, I will start explaining advanced options.
;THEY GENERALLY SHOULD NOT BE SET, except if something does not work.

;option set below. So instead of making me do extra work, just don't set the

;##############################################################################
;The first advanced option is "delay". Delay is a number of microseconds to
;delay the application boot.
;Why this is important? It may improve the booting of some homebrews and CFWs.
;For example, O3DS autobooting with themehax, using either rxTools or
;CakesFW with Brahma2 loaders will have increased boot rate chance with 100
;ms of delay. For Homebrew Launcher (and other homebrews) the delay may be
;set to 0, unless your homebrew needs network connection during boot (such as
;FTBrony 1.x). In this case you may increase the delay (for example to 5000,
;or 5 seconds) to makes sure that you have a valid network connection.
;By default delay is set to 1500 (1.5s). This is a value that seems to work
;well with CFWs, without delaying the boot of homebrews by too much.

;Instead of loading .3dsx files, you can use ARM9 payloads like rxTools'
;code.bin or CakesFW's Cakes.dat. By default it will try to detect if the
;file is a payload by checking the extension (.bin or .dat), however you can
;force by passing "payload = 1" (passing "payload = 0" forces homebrew mode,
;while "payload = -1" forces autodetect, the default).
;You may need to change the default payload offset depending of the binary
;you're loading. The values are generally in hexadecimal, so append "0x" in
;front of the number (however, decimal values are supported too).
;The default offset (0x12000) works in RxTools/CakesFW/ReiNand.
;Don't worry about setting offset option in .3dsx files, it is ignored.

;Splash is a screen that shows while BootCtr is loading, showing information
;about the current entry in the bottom screen and a nice logo in ASCII art in
;top screen, or optionally any image converted in the BGR format.
;However, you can disable BootCtr splash screen in each entry by passing
;"splash = 0". Disabling it may avoid garbage screens while booting in
;some cases (i.e. Homebrew Launcher).
;WARNING: this option only enable/disable splash screen, however the actual
;duration of splash is controlled (indirectly) by "delay" option. If you want
;to increase the duration of splash, for example, set a higher delay. Setting
;"delay = 0" does not disable splash either, however it may be too fast to
;read.
;To use an image instead of the default ASCII art, you need to pass a converted
;BGR file to the "splash_image" option. Use the site below to convert files:

;[GLOBAL] is the only section that you may not set "path" option, however you
