SPC7110 Check Program#
Like Tengai Makyou Zero and Momotarou Dentetsu Happy, this game makes use of the SPC7110 co-processor. A test program for it is loaded on boot if the internal battery dies or the SRAM gets corrupted and it's a later version than the one in Tengai Makyou Zero, being v3.0 instead of v2.2.
As it has only a few differences from the precedent version, this section illustrates the new version as a comparison against the old one:
Mode 1#
Prompt
|
v2.2 |
v3.0 |
|---|---|
|
|
The prompt is written in English in this new version. That PUSH A BUTTON prompt is confusing as only pressing the A button makes the first test battery start. Also, this mode is loaded even if only a single byte of the SPC7110 CHECK OK string was altered in some way (but not all are equal to 0x11 like in the precedent version).
On Test
|
v2.2 |
v3.0 |
|---|---|
|
|
The RTC TIME test is absent in this version, as this game doesn't use any kind of RTC.
Pass
|
v2.2 |
v3.0 |
|---|---|
|
|
Unlike the older version, in v3.0 everything is written in English with the same font.
Fail
|
v2.2 |
v3.0 |
|---|---|
|
|
Behaves in the same way of v2.2.
Mode 2#
Prompt
|
v2.2 |
v3.0 |
|---|---|
|
|
Again, the prompt is written in English in this version.
On Test
|
v2.2 |
v3.0 |
|---|---|
|
|
No RTC BACKUP test is performed, for the same reason explained above about the RTC TIME one.
Pass
|
v2.2 |
v3.0 |
|---|---|
|
|
ALL OK is written with the same font of all the other text, like what happens in this case on the precedent test.
Fail
|
v2.2 |
v3.0 |
|---|---|
|
|
Also in this case, it behaves in the same way of the precedent version.
Oddity#
The oddity found in the precedent version of the test program is still present.
