Hi everybody!!!
I don't know if somebody is still interested in this kind of devices, but i'll put in this thread all i've discovered since last Time:
1.- I download the source code of firmwares from this post:
FULL firmware 9.1.51 (ACU7515) - HELP !!! I need it
This is the Rapidshare links:
ACU7515_9_1_51_NODRM_20070329.rar
ACU7515_9_1_51_DRM_20070329.rar
2.- I found the compiler for this sources, is the IAR Embedded Workbench for Zilog Z80 (the version must be previous to 4.06a because if i try to open any *.prj file the program gives me this message "
The project file is in an old format, Convert it for use with this version?")
4.- I can't Make any project because i always have the same error in ap_common.c file:
d:\case_i_d912f\ap\common\ap_common.c (62) : Error[128]: Function argument incompatible with its declaration
d:\case_i_d912f\ap\common\ap_common.c (97) : Error[128]: Function argument incompatible with its declaration
5.- I try to use the *.ap files already compiled from the source code with my ak1025 and a acu7515 i've just buy (to test) but doesn't work (clocks appears forever, i recovered using s1clone and previous backups), maybe the problem is the version of the firmware (the sources are 9.1.51 and both players are 9.1.52)
I stop at this point, i try many many things like to put any kind of file in the fwimage.fw (inclusive a renamed copy of UI30.RES) but the same, just the sandclock appears. the only file i could put in the firmware and the player starts normally is the s1first test from
s1mp3.de renames as record.ap, but if i try to use the record i got a black screen.
I found in this page a firmware called case_i_d915f (inclusive a case_i_d915f from 20090617), appears that this is more recent and with many others exe files we can use, but this page only show the list of files they sell in a big package (26 DVDs) for about US$ 100 (the price is not the problem, but i think itīs scam, you pay and never receive something). If somebody has this new firmware (and wants to share
), please go ahead!!!
