(SOLVED) 41CL - DOUBLE HEPAX ACCESS and MMU CONFIG

[Podalirius]

Hi, I tried to install your instructions, but I have a little problem:
I executed:
ON <--, MEMORY LOST
MMUDIS
MMUCLR
"YFNX" PLUG1U
"YFNF" PLUG2L without it I am not able to use CFGINI
MMUEN
I saved this in MMU 0 and MMU 1 as a backup
XEQ CFGINI
XEQ RCLCFG 4
"WARP 7" XEQ PPLUG
ERROR LOCK
I tried UNLOCK 7
OK
"WARP 7" PPLUG
ERROR DUPLICATE ROM 15
BAD CONFIGURATION
I stopped. I need more help or I am useless at 41CL!!
Maybe it is because my first pocket computer was an hp 48SX,
than I used/programmed hp 48GX, 49G and now the 50g.
It is possible that I not understood the logic of the 41CL.
Anyway, I thank you so much!!
