Icon tooltypes and stuff

oRBIT · 22 April 2010, 19:13

I have a new idea for my NES emulator. Imagine starting a ROM directly using a icon instead of loading it using the regular emulator-interface.
Wouldn't it look cool? Having a SuperMarioBros icon on your workbench and when you doubleclick it, the game will start as any other Amiga-game.
My question is, what's the best way of doing this (I haven't done much icon-related coding in my days..)
My first thought was something like, when the user clicks the game-icon, A/NES starts with an argument, something like:
"ANES SuperMarioBros.nes"
Is there a smarter way of doing this?

I wonder how you want to do this from an icon. You'd need an extra script file for each ROM.

The Amiga way of doing this is to make project icons for the ROMs with ANES as the default tool.

In ANES you then examine the startup message you get from Workbench. It contains a pointer to a struct WBArg which contains the lock of the directory the ROM was started from and the name of the ROM file.

If ANES and games could be started from shell with arguments that would be GREAT.

Eg- ANES Turtles.NES

I could add NES games along side Amiga games in my AGS boot menu or have a separate AGS menu for NES games.

Thanks, I'll investigate this for sure. I'm not that used to OS-friendly coding so I'll hope I find out how it works.

Here is an example:

Code:

#include <proto/exec.h>
#include <proto/dos.h>
#include <workbench/startup.h>

int main (int argc,char **argv)

{
struct WBStartup *wbmsg;
BPTR win;

if (argc != 0)
	{
	Printf ("This program cannot be run in DOS mode :-)\n");
	return (RETURN_ERROR);
	}

wbmsg = (struct WBStartup *)argv;

if (win = Open ("con:0/0/640/400/WB Icon/CLOSE/WAIT",MODE_NEWFILE))
	{
	char buffer[256];
	long i;

	NameFromLock (wbmsg->sm_ArgList->wa_Lock,buffer,256);
	AddPart (buffer,wbmsg->sm_ArgList->wa_Name,256);
	FPrintf (win,"Program name: <%s>\n",buffer);

	for (i = 1; i < wbmsg->sm_NumArgs; i++)
		{
		NameFromLock (wbmsg->sm_ArgList[i].wa_Lock,buffer,256);
		AddPart (buffer,wbmsg->sm_ArgList[i].wa_Name,256);
		FPrintf (win,"Argument #%ld: <%s>\n",i,buffer);
		}

	Close (win);
	}

return (RETURN_OK);
}

An example in asm would be even better, but thanks.

@Offtopic:
"pea"? Isn't that one of the "missing" instructions on the 68060 that has to be emulated?

Nope, pea is not missing on 68060. movep is not supported on 68060.

Ah thanks

oRBIT · 27 April 2010, 20:37

By studying the source for awhile I just realised I am gonna fail with this task, pretty bad, since I haven't got a clue what's going on.
If anyone feels up for the task and have some free time, please let me know.

I'm happy to announce that the next major release of A/NES will have commandline-support (just like you described above), for example:
1>ANES SuperMarioBros.nes

Sounds good

I look forward to the next release I dont want to be pickey but could you add Frame Skip

oRBIT · 28 April 2010, 10:23

@BooBoo:
A simple frameskip is already implemented in the next release. However since all the major changes I've done, you'll still require a pretty fast Amiga (at the moment anyway) to make the games enjoyable.
So if you haven't got yourself a 060 yet, now is the time.

The major question is, is you code already be able to be started from Workbench (i.e. by double click on its icon) ? Or does it crash if you try it ?

Of course you first have to make it startable from Workbench. This means you need to check if pr_CLI is set and if not, you should receive the WBStartup message from the process' message port.

Once you've got the message, it should be rather easy to read the sm_ArgList array which contains pointers to the program itself and each project icon which was highlighted when the program was started.

oRBIT · 28 April 2010, 12:15

@Thomas. Yes, I've got special startupcode that makes it run properly from an icon (haven't written it myself however..)

thomas · 28 April 2010, 13:20

I've changed the example to include the necessary startup code:

Code:

#define __NOLIBBASE__
#include <proto/exec.h>
#include <proto/dos.h>
#include <workbench/startup.h>

struct Library *SysBase = NULL;
struct Library *DOSBase = NULL;

#ifdef __VBCC__
#define __D0 __reg("d0")
#define __A0 __reg("a0")
#endif

long start (__D0 long arglen,__A0 long argstr)

{
struct Process *pr;		/* pointer to own process structure */
struct WBStartup *wbmsg = NULL;	/* pointer to startup message */
long rc = RETURN_FAIL;		/* return code */

SysBase = *((struct Library **)4);	/* store pointer to ExecBase in local variable */

pr = (struct Process *) FindTask (NULL);	/* get pointer to own process structure */

if (!pr->pr_CLI)	/* check if run from Workbench */
	{
	WaitPort (&pr->pr_MsgPort);	/* yes -> wait for startup message */
	wbmsg = (struct WBStartup *) GetMsg (&pr->pr_MsgPort);	/* and fetch it */
	}

if (DOSBase = OpenLibrary ("dos.library",36))	/* open dos library */
	{
	if (!wbmsg)	/* if not run from Workbench print message and quit */
		{
		VPrintf ("This program cannot be run in DOS mode :-)\n",NULL);
		rc = RETURN_ERROR;
		}
	else
		{
		BPTR win;

		/* open a console window */
		if (win = Open ("con:0/0/640/400/WB Icon/CLOSE/WAIT",MODE_NEWFILE))
			{
			char buffer[256];
			long i;
			struct {
				long n;
				char *p;
				} va;		/* arguments for VFPrintf */

			va.p = buffer;

			NameFromLock (wbmsg->sm_ArgList->wa_Lock,buffer,256);	/* get name of directory of first icon in sm_ArgList */
			AddPart (buffer,wbmsg->sm_ArgList->wa_Name,256);	/* add name of file */
			VFPrintf (win,"Program name: <%s>\n",&va.p);		/* print to the window */

			for (i = 1; i < wbmsg->sm_NumArgs; i++)		/* walk through all project icons */
				{
				NameFromLock (wbmsg->sm_ArgList[i].wa_Lock,buffer,256);	/* get name of directory */
				AddPart (buffer,wbmsg->sm_ArgList[i].wa_Name,256);	/* add name of file */
				va.n = i;
				VFPrintf (win,"Argument #%ld: <%s>\n",&va);		/* print to the window */
				}

			rc = RETURN_OK;	/* set good return code */

			Close (win);	/* close console window */
			}
		}

	CloseLibrary (DOSBase);	/* close dos library */
	}

if (wbmsg)	/* if run from workbench */
	{
	Forbid();		/* forbid task switching until this task ends */
	ReplyMsg (&wbmsg->sm_Message);	/* return startup message to sender */
	}

return (rc);	/* set return code and quit */
}

I've also attached the compiled version and an example project to test it.

I appreciate your effort Thomas, but I can't get the asm-output to run in AsmOne, it just refuses and gives me lots of problems.
Wonder if there's an easier way for me to implement this... hm..

I know I sound like a nag, but if you switch to a more modern assembler and use a linker then you can link M68K object code from any compiler or assembler together without hassle. ASM-One is really neat, but as an end-all be-all development tool it is very poor.

You can adjust Thomas' code by removing the procstart, procend and debug statements (they are obviously not M68K assembly), remove the ds.w 0 statements in the end, or replace with even if that doesn't work, and find the l30 label and move the registers specified to the movem.l instruction farther up that references them.

Imagine starting a ROM directly using a icon instead of loading it using the regular emulator-interface. Wouldn't it look cool? Having a SuperMarioBros icon on your workbench and when you doubleclick it, the game will start as any other Amiga-game. My question is, what's the best way of doing this (I haven't done much icon-related coding in my days..) My first thought was something like, when the user clicks the game-icon, A/NES starts with an argument, something like: "ANES SuperMarioBros.nes" Is there a smarter way of doing this?

Eg- ANES Turtles.NES I could add NES games along side Amiga games in my AGS boot menu or have a separate AGS menu for NES games. Last edited by Retro1234; 22 April 2010 at 20:13.

If anyone feels up for the task and have some free time, please let me know.

oRBIT Zone Friend Join Date: Apr 2006 Location: Gothenburg/Sweden Age: 48 Posts: 344	@BooBoo: A simple frameskip is already implemented in the next release. However since all the major changes I've done, you'll still require a pretty fast Amiga (at the moment anyway) to make the games enjoyable. So if you haven't got yourself a 060 yet, now is the time.
