MEGA~CD SOFT CHECK MANUAL
+ HOW TO USE "CHECK CARTRIDGE AND "CHECK CD"
* CARE HAS TO BE TAKEN THAT IF THIS CHECK IS PERFORMED, THE DATA OF THE BACKUP RAM ARE ERASED OR REWRITTEN.
1. Make sure that the power is turned off beforehand and then install a Mega Drive on the MEGA-CD to be checked.
2. Connect the Joypad to the Control No.1 of the Mega Drive
3. Install the check cartridge on the cartridge connector of the Mega Drive.
4. Turn the switch of the Mega Drive on.
5. Checking starts when the START button of the Joypad is pressed.
6. The tray opens during the checking. Install the check CD.
7. If the checking is completed, the tray opens again. Remove the check CD.
+ CAUSE OF ERROR IN EACH CHECK ITEM
* MEGA-CD INTERFACE PART
1. Boot ROM Read check
Read the boot ROM (IC4) in the MEGA-CD from the Mega Drive and check if it is in the normal conditions.
Cause of Error: Connector board (Connector pin contamination, IC defect, pattern disconnection etc.), Boot ROM defect (IC4), etc.
• If the boot ROM is EPR-14088A (Version A), it always resul~s in error. The software itself of this boot ROM has many bugs; therefore replace it with the latest ROM.
2. Program RAM R/W check
Perform R/W onto the program RAM (IC5 to ICB) and check if the access to the RAM is normal.
Cause of Error: Defect of IC5 to ICB, pattern disconnection, surroundings of GA (IC2) etc.
1
3. BIOS transfer 4. System transfer
Transfer the data of the BIOS (collection of programs for each of the functions to have sub-CPU access to the CD drive) and the data of the system (program that has used the BIOS) from the check cartridge to the program RAM. Distinction is being made only based on what kind of dated is being transferred to the program RAM; therefore, the "2 program RAM R/W check" and the error of the above 3 and 4 occur due to the same factor in terms of hardware.
Cause of Error: Same as 2
4. Sub-CPU reset check
The MEGA-CD system is equipped with the CPU (68000 & Z80) of the Mega Drive side and the CPU (68000 (ICl) ) of the MEGA-CD side. For the sake of convenience, the former is called the main CPU (or main side) and the later is called sub-CPU (or sub side). Here, try resetting from the Mega Drive side to the sub-CPU and check if a normal response is returned.
Cause of Error: ICl defect, the surroundings of G/A (gate array IC2) etc.
* COMMUNICATION CHECK
Check if the communication between the Mega Drive side and the sub-CPU (ICl) goes well or not. The circuit of this purpose is located in the G/A (IC2); therefore, the cause of error may include G/A (Ic2) and sub-CPU (ICl) etc.
Cause of Error: the surroundings of G/A(IC2), sub-CPU (ICl) etc.
1. Communication flag R/W check
Perform R/W on the flag (inside G/A) required for communication and check if they function properly.
2. Communication port
Access the communication port (in G/A) and check its function.
3. Stopwatch check
Check the function of the watch located in G/A.
2
3J
* WORD RAM PART (IC11,_IC12)
Check the functions related to the word RAM (ICll, IC12). The word RAM executes programs and performs data processing for graphic rotation etc. Causes of Error here can include
·the G/A (IC2) and word RAM parts.
Cause of Error: the surroundings of G/A (IC2) and word RANG (ICll, IC12), pattern disconnection between the two.
1. 2. 3. 4. 5. 6. 7. 8. 9.
10. 11.
• if there are some passing items in the followings, the possibility of pattern disconnection is considered to be low.
2M mode R/W check 2M mode select check Graphic mode check Graphic overwrite mode check Graphic underwrite mode check 1M mode R/W check 1M mode swap check 1M mode overwrite mode check 1M mode underwrite mode check VRAM image check Word RAM to VRAM DMA check
* PERIPHERAL IC
Check peripheral res. One is to check the access to the PCM RAM (IC13, 14), and another is to check the function of the backup RAM (IC10).
1. PCM wave memory R/W check
Cause of Error: the surroundings of PCM IC (IC3) and PCM RAM ( IC13, 14)
2. Backup RAM check
Cause of Error: the surroundings of Backup RAM (IClO), battery (BTl), backup power control IC (IC9)
* CD INTERFACE PART
Check whether the interchange with the CD drive can be carried out properly, or whether the CD drive itself operates properly.
Cause of Error: the surroundings of G/A (Ic2), CNl, the connect -ing cable between CNl and CD drive etc.
3
33
1. CD-DRIVE connection check (Communication)
2. TOC Read check
3. Sub-code read check
* CD-DATA READ CHECK
Check CD data itself read by the CD drive and data processing.
Cause of Error: the surroundings of G/A (IC2), CNl, the connect -ing cable between CNl and the CD drive, the CD drive , CD (IC15) etc.
1. SUB CPU Read check
2. Main CPU Read check
3. Program RAM DMA check
4. PCM RAM DMA check
5. Word RAM 1M mode DMA check
6. Word RAM 2M mode DMA check
* SOUND CHECK
Actually replay the CD sound and listen to it with your ears for checking.
Cause of Error: CN3, the connecting cable between CN3 and the sub-board, the sub-board etc.
1. CD-DA check (Replay of the 14th music of the check CD)
