Quote from: WacKEDmaN on 14:43, 01 July 22thanks ikonsgr... unfortunatly i dont have a PIC programmer... it would be nice if these could be updated over serial or the usb.. maybe something for the future..

Quote from: WacKEDmaN on 11:02, 02 July 22i have tried another ribbon and connector from a lower rom board (that works perfectly fine)the cpc464 board im using is a new replica board.. the fingers on the edge connector are quite nice...(and ive cleaned them 3 times now!)im starting to think..my board "may" have slightly longer traces or impedances that are throwing off the timing.....a few little things ive noticed...there is a through hole resistor on the back of this board.. i cant see any resistors on any of pics of the boards or the schematic in this thread.. is it supposed to be there?! (1.2Kohm)also there seems to be a SMD capacitor missing (C6) on the USB module.. ..but that "shouldnt" be causing any issues tho...
Quote from: WacKEDmaN on 11:35, 02 July 22right...so i should remove the resistor, and put the 1N4148 in as shown?

Although it's rather strange that your brand new CPC464 replica board doesn't work right with fw 6c and the pull up resistor...
Quote from: WacKEDmaN on 11:43, 02 July 22it had 6d on it when i got it...i found you firmware repo.. and just flashed 5a..but just got a yellow screen!..ill reflash 6d and do these hardware changes (i hope ive got a spare 1N4148 handy!) and see how it goes...
Quote from: ikonsgr on 18:00, 02 July 22Yes, diode should be placed under dsk swap button. But even without the diode, Amstrad CPC464 should boot normally (actually it should boot twice on cold start) Anyway,from what you describe, it seems there might be signal problems with this replica board and USIfAC board. It reminds me the same erratic behavior with previous versions of RAM/ROM board, where the added length of signal traces, caused problems because of the 1oz copper thickness and relative thin traces. When i used 2oz copper thickness and wider trace widths (especially for 5v & gnd), most problems resolved. Maybe something similar happens with this replica board...
Quote from: ikonsgr on 18:23, 02 July 22One last thing:i remember that some people had problems flashing PIC using PICKIT3, when hex file was code protected, so try this unprotected file and see if it works:You cannot view this attachment.
Quote from: shacpc on 23:16, 30 June 22Quote from: wolfgang on 21:53, 30 June 22The USB stick is formatted with FAT32 and I tried with 2 different USB sticks, I did copy the content in the sticks root directory, not the folder.Thanks anyway for your reply, I will try again when I have upgraded the USIFAC II to the latest firmware, could be the problem as eto just mentioned.Precisely the "basic" structure of LILICPC is like this to ensure the greatest compatibility of USIFAC devices (past and future) and because 100x100 games work perfectly with this launcher system and ease of use for any user, because I do not plan give support and for that reason I decided to include this "plus" for usifac in this cpcwiki post, which ikonsgr has kindly allowed.In the beginning, the idea about LILICPC was to create a menu system with a basic program, but there were occasional failures in the execution of games and in the reset and it also prevented the enormous amount of games that can now be played with LILICPC.When ikonsgr launches the ULIFAC I will publish in this post a new update with 1000 more games and with a much more optimized LILICPC.As I always say, all credits and thanks from LILICPC to the creator of USIFAC Ikonsgr and to the authors of the games.

Quote from: wolfgang on 23:39, 02 July 22I got m,y PIC programmer and updated the USIFAC to Version 6d, the RUN"xxx now works.Only thing is it works only once, after resetting USIFAC II another RUN"xxx command gives "File not found", so I have to switch OFF/ON the CPC464.Anyway the effort of reseting USIFAC or OFF/ON the CPC is nearly the same, so I think its not worth to put more effort on it.LILICPC is actually a very nice collection, many thanks for your work, as well as to ikonsgr for the fantastic USIFAC II.GreetingsWolfgang
