This module has the size of 58.656 ( $E520) bytes and thus plenty of space for additional modules. Open the file impega63.rom with a hex editor and locate address $11AD6 вЂ“ the start of the module dummy.

On the way, weвЂ™ll learn a lot about OS-9 modules in the OS-9 2.4 Technical Manual ( Memory Modules, pages 1-7 ff). For now, just remove 128 KB from either the beginning or the end of the file. This will be fixed in future versions of the tool. Note: At the time of writing this article, cdilink is overdumping DVC ROMs and creates 256 KB files. This is what you should get: impega63.rom (ID 10, R6.3, CRC 861E0F38).

#PHILIPS CDI EMULATOR DVC HOW TO#

Refer to the section above on how to dump the ROM. Philips 22ER9956/40 mini DVC: Removing the ROM and fitting a socket Then, use the desoldering gun again from the bottom until the chip is free. by heating them up and removing as much solder as possible with desoldering wick. Some of them are very persistent and need additional work from the top, e.g. Then, use a powerful desoldering gun because the pins are soldered from both sides. To remove the EPROM, first apply flux and fresh leaded solder to all pins.

But IвЂ™ve seen socketed EPROMs before and if this is the case with your DVC, you can skip the following step. Remove the DVC and inspect it: Usually, it has a 27C1024 EPROM soldered to the PCB. HxD), select 16.144 ($3F10) bytes starting from address $34F2A and copy them to a new file (e.g. YouвЂ™ll get the right address with cdilink -info. DonвЂ™t worry if your player has a different revision of the ROM the module sv should be the same for all 490 ROMs and is only located at a different address. The module sv starts at address $34F2A, has the size of 16.144 bytes and the 24-bit CRC 411228. This is the ROM I was using: cdi490a17.rom (ID 77, R1.7, CRC 9A10DA73). In order to actually run CD-i software, the emulator needs copies of the CD-i system ROMs. Srec_cat cdi490a.rom -binary -byte-swap 2 -o cdi490a_swap.rom -binary CD-i Emulator using CD-i 370/00 ROMs (1/2) CD-i Emulator using CD-i 370/00 ROMs (2/2) The CD-i Emulator program provides a fairly complete emulation of the hardware of an actual physical CD-i player. If the programmer software doesnвЂ™t support that, you can use the SRecord tools to convert it. If you are using an EPROM programmer, make sure to save the file in little-endian format. You can dump it either via CD-i Link (option -roms) or with an EPROM programmer. Prerequisite: sv moduleДЇirst of all, youвЂ™ll need the dump of a CDI490 system ROM.

In this article, I will show you a simple ROM patch to enable the Service Shell for the CDI660. When CD-i Emulator with -testplug option showed the same behaviour, CD-i Fan figured out what is causing this error: The Service Shell module sv is missing from the 660/670 system ROM.

However, this wasnвЂ™t a very practical approach because I had to open up the player and dig out the system ROM from underneath the DVC every time. My solution so far was to use a 490 system ROM in the 660 whenever I needed the Service Shell (the compatibility and also the error were discovered during this experiment). I expected it to boot into the Service Shell, like most other CD-i players. For quite some time, I was puzzled why my CDI660 was stuck in a reset loop after I inserted the test/dummy plug into Input 1.
