Elmer's PC Engine Programming Resource Links

[elmer]

Another PC Engine resource has gone titsup!

Emanuele Bettidi's website with his PCE Joypad schematics has disappeared, and it isn't available in the Wayback Machine ... so I've uploaded the files to flickr and updated the links at the top of this thread.

Updated the "no-eyestrain" version of Mednafen to v1.22.2, and added disassemble-to-file and hex-dump-to-file functions which can be useful for translation-hacking.

The disassembler itself is new, and adds a couple of features over Mednafen's original version.

Anyone developing a PCE game or utility specifically for the Turbo Everdrive hardware can now set the entire 1MB of Mednafen's cartridge space to writable-RAM to simulate the TED2 for debugging.

Please wait a few days; I have something interesting and System-card-related coming very soon...

HuC developers are directed to Turboxray's github project page for the latest developments and Windows binaries for HuC. Thanks Turboxray!


Updated the "no-eyestrain" version of Mednafen to v1.27.1, with only a 64-bit Windows build provided.

This is now cross-compiled on linux for extra speed, and because compiling with MSYS2 is currently broken due to changes in Mednafen and bugs in MSYS2.

Added documentation to the first post for the recently-added ISOlink CD-ROM File Directory.

[elmer]

Moved the ISOlink CD-ROM file directory from the 1st sector of the ISO to the 2nd sector of the ISO, because the PC-FX needs an unmodified 1st sector in order to display its error message when putting a PCE CD into the PC-FX.

[elmer]

Slight changes to ISOlink directory format, and to ISOlink's command line, primarily so that folks using a custom IPL-file can still set their project's title in the information block.

I have a question related to the NESASM update - I was using versions 3.0 and 3.1 before, when I changed to the latest v3.23-c266d57 Beta, there started to appear compilation errors that were not in 3.0 and 3.1, for example:



NES Assembler (v 3.23-c266d57 Beta, 2018-07-07)



pass 1

pass 2

#[2]   famitone\music.asm

   6  0E:C559                  .dw .samples-4

      Undefined symbol in operand field!

# 1 error(s)

Is ".dw .samples-4" no longer supported? (dash at the end of define word)


The code with which the new NESASM had a problem:

Thanks for the bug-report!

I have checked the old 2018 build that you're using, and can confirm the problem that you're seeing.

I wonder what-on-earth is going on!


The thing is, that build is 3 1/2 years old now, and the current NESASM v3.25 (built from the sourcecode in github) does not exhibit the bug that you're reporting, and so there's no way that I can track down a problem that doesn't *seem* to exist anymore.

Can you please either build the toolchain from the current source (if you're on Linux/Mac), or if you're using Windows 64-bit, you can try this updated NESASM ...

<EDIT> Attachment removed!

I think there are some files in the archive that clash with Windows 10 Defender because I can't download: "Trojan: Script / Sabsik.FL.A! Ml".

<sigh> OK, Windows can be a bit paranoid, especially with a .zip file that only contains a one file, a .exe file.

I have added a new complete Win64 build of the current HuC to the first post in this thread.

Can you please see if Windows will let you download that?

[siudym]

Everything works. The error is no longer present.

Is it possible to add an option to set the size of attached files in INCBIN? Currently, the BIN file is attached in its size, I miss the possibility to set how many bytes should be included (NESASM / PCEAS).


Like other asemblers, eg WLA:

.INCBIN "file.bin" READ 672                              ; read/attaches 672 bytes from binary file.

Hi! The link to the HuC automated windows build is broken

I've fixed the links in the 1st post to point to the official PCE-DEVEL github group now that it exists. :-)

My original repo was transferred to the PCE-DEVEL group, and I have forked a new personal "work-in-progress" repo from that group in order to keep everything clean.
