| Description | C+4 Emulator Test Suite - Public Domain, no Copyright
based on c64 Test Suite
The purpose of the C+4 Emulator Test Suite is
- to help C+4 emulator authors to improve the compatibility
- to ensure that updated emulators have no new bugs in old code parts
The suite are a few hundred C+4 programs which check the details of the C+4
they are running on. The suite runs automated and stops only if it has
detected an error.
That the suite doesn't stop on SVS C+4 (PAL) proves that the suite
has no bugs. That the same suite doesn't stop on an emulator proves that this
particular emulator is compatible to SVS C+4 regarding every tested
detail. Of course, the emulator may still have bugs in parts which are not
tested by the suite. There may also be a difference between your C+4 and
SVS C+4.
While the Test Suite is running, the Datasette should be disconnected. Needs
about 70 min to complete.
The source code for C64 has been developed with MACRO(SS)ASS+ by Wolfram
Roemhild. I used Macro Ass+ improved by mr. Mind in 1993 (Turbo-Ass Mac+
extended version (c) Omicron). You should use C64 or C64 emulator to compile
sourses. The program BRANCHWRAP had no source in the original Test Suite for
C64.

Program _START - some 6510 basic commands, just as an insurance
///////////////////////////////////////////////////////////////////////////////
Programs LDAb to SBCb(EB) - 6510 command function
addressing modes
-----------------------------------
n none (implied and accu)
b byte (immediate)
w word (absolute for JMP and JSR)
z zero page
zx zero page,x
zy zero page,y
a absolute
ax absolute,x
ay absolute,y
i indirect (JMP)
ix (indirect,x)
iy (indirect),y
r relative
Display:
before data accu xreg yreg flags sp
after data accu xreg yreg flags sp
right data accu xreg yreg flags sp
Either press STOP or any other key to continue.
All 256 opcodes are tested except HLTn (02 12 22 32 42 52 62 72 92 B2 D2 F2),
ANEb (8B), LXAb (AB). Two last instructions algorithm for c+4 is still
undescovered. :-(
Indexed addressing modes count the index registers from 00 to FF.
JMPi (xxFF) is tested.
Single operand commands: 256 data combinations from 00 to FF multiplied by 256
flag combinations.
Two operand commands: 256 data combinations 00/00, 00/11, ... FF/EE, FF/FF
multiplied by 256 flag combinations.
LASay, SHAay, SHAiy, SHXay, SHYax and SHSay are executed only in the y
border. These commands cause unpredictable results at c64 when a DMA comes
between the command byte and the operand. It is left unchanged for c+4.
SHAay, SHAiy, SHXay, SHYax and SHSay are tested on a data address xxFF only.
When the hibyte of the indexed address needs adjustment, these commands will
write to different locations, depending on the data written.
///////////////////////////////////////////////////////////////////////////////
Programs TRAP* - 6510 IO traps, page boundaries and wrap arounds
# code data zd zptr aspect tested
-----------------------------------------------------------------------------
1 3000 31C0 F7 F7/F8 basic functionality
2 2FFE 31C0 F7 F7/F8 4k boundary within 3 byte commands
3 2FFF 31C0 F7 F7/F8 4k boundary within 2 and 3 byte commands
9 3000 31C0 02 F7/F8 wrap around in zx and zy addressing
10 3000 31C0 00 F7/F8 IO traps for 8 bit data access
11 3000 31C0 F7 02/03 wrap around in ix addressing
12 3000 41C0 F7 FF/00 wrap around and IO trap for pointer accesses
13 3000 0002 F7 F7/F8 64k wrap around in ax, ay and iy addressing
14 3000 0000 F7 F7/F8 64k wrap around plus IO trap
16 FFFE ---- -- --/-- 64k boundary within 3 byte commands
In the program TRAP16, the locations of data, zerodata and zeroptr depend on
the addressing mode. The CPU port at 00/01 is not able to hold all 256 bit
combinations.
Display:
after data accu xreg yreg flags
right data accu xreg yreg flags
If all displayed values match, some other aspect is wrong, e.g. the stack
pointer or data on stack.
All 256 commands are tested except HLTn/ANEb/LXAb. Registers before:
data 1B (00 01 10 11)
accu C6 (11 00 01 10)
xreg B1 (10 11 00 01)
yreg 6C (01 10 11 00)
flags 00
The code length is 6 bytes maximum (SHSay).
When the lowbyte of the data address is less than C0, SHAay, SHAiy, SHXay,
SHYax and SHSay aren't tested. Those commands don't handle the address
adjustment correctly.
Relative jumps are tested in 4 combinations: offset 01 no jump, offset 01
jump, offset 80 no jump, offset 80 jump. For the offset 80, a RTS is written
to the location at code - 7E.

Program BRANCHWRAP - Forward branches from FFxx to 00xx
Backward branches from 00xx to FFxx were already tested in TRAP16.

Program MMUFETCH - 6510 code fetching while memory configuration changes
An example is the code sequence STA $FF3E : BRK in RAM at Axxx. Because
STA $FF3E maps the Basic ROM, the BRK will never get executed.

This program was considerably rewritten for C+4. It is possible to
compile its source under C+4 with C+4 port of Turbo Assembler. It works
under single clock mode.

To do...
Tests for IRQ, IMR, and timers are not converted. Tests for TED/ACIA/PIO/...
are missed. :-( Feel free to add them!
