New MAME release

Recommended Posts

That's cool, thanks. When I said "not useful", I actually meant "nothing". 🙂

 

So I guess this will be really helpful.

 

However, first on the list is to finish the IDE card; I found some flaws in my BQ4847 implementation. I'm also in contact with Fred who was able to fix some parts in his IDEDSR; I guess there will be a new release soon.

Discovered a little factoid using the MAME 99/8 with hexbus & DSSD disk. the 99/8 won't load an old XB TI-99/4a program saved in INT/VAR format. PROGRAM format is just fine though. if the file is too big I guess you'll have to split it up and re-merge (which I haven't tried) on the 99/8.

Not sure, but on the normal TI's you could do CALL FILES(1) (and CALL FILES(2), something like that), before loading larger programs and I remember with Personal Record Keeping (PRK) and Personal Record Generator (PRG) you could load bigger programs as well and some could only be loaded in TI-BASIC  (and not in Extended Basic).

Seems as if the HX5102 does not support the long format (I/V254) at all, regardless of the file size.

 

Note that the TI-99/8 has a lot of CPU RAM and, as fas as I could see, does not need to use VDP RAM for disk operations, so it can create longer PRG files. This certainly breaks compatibility with the TI-99/4A. Anyway, things are broken long before; for example, Extended Basic II puts the PAB into CPU RAM, which crashes standard TI disk controllers.

so the work around is to split the ti99/4 files then MERGE them back. a pain, if works, should, but doable.

Hmm this sounds like a Broken Flag problem in XB?

I haven’t tried it yet, but the 99/8 is supposed to be able to “OLD” programs that were LISTed to a device.  Can you do a LIST “DSK1.FILE” on the 99/4A of the INT/VAR program and then OLD it on the 99/8?

doesn't seem to work. unfortunately, neither does SAVE"DSK1.FILE",MERGE then on the ti99/8 MERGE"DSK1.FILE" it gives an error I/O error 4. doesn't matter size of file just gives error anyway. thing is, we don't know if TI ever intended to be able to transfer XB files seamlessly from the 99/4 to the 99/8?

@senior_falcon has a sub-program in TML that converts PROGRAM files to IV254 format, the opposite of what we want done. something like that might been needed and maybe it was TIs intention to release such?

You have to consider that a) the engineers were happy to get to an end with the machine with all the pressure behind (and then failing after all) and b) at some time you just do not and cannot care about older systems if you want to exploit the whole potential of a machine.

 

I can also imagine that the engineers noticed that Extended Basic II does not work with the old TI controller, but management required to support the Hexbus ("Hexbus first!", but second came nothing...)

It seemed to work ok for me, but with some issues.

 

I don't have any Extended BASIC programs large enough to be saved as INT/VAR 254.  But I do have a few large TI BASIC programs from the Oldies but Goodies Games I cassette that I played around with.

 

Word Scramble - I did a LIST "DSK1.WORDLIST" and then NEW and OLD DSK1.WORDLIST - it failed with * Unmatched quotes but it loaded some number of lines before it hit that.   I suspect that was due more to the : print separators from TI BASIC messing up Extended BASIC II.

Tic Tac Toe - SAVE DSK1.TICTACMRG,MERGE followed by NEW and MERGE DSK1.TICTACMRG worked correctly.

 

I'm using Mame v0.198 for my testing (if it makes a difference).

maybe I did something different. how did you do it?

by the way, here are some XB programs I wrote:https://ti99resources.wordpress.com/software/

go down to 'My Games' were i have a bunch BASIC & XB games to test with.

I used your Mille Bourne game to test with.  

 

On the 99/4A in Extended BASIC, I exited the game that autostarted, and then did OLD DSK1.MILL34 followed by SAVE DSK1.MILMRG,MERGE

I then got into the 99/8 and MERGE DSK1.MILMRG - that seemed to work just fine.

SAVE DSK1.MILL34 saved it as INT/VAR 254 as expected.

 

One thing interesting - your disk image shows different file types if it's in the 99/4A or 99/8 when using Disk Manager 3 to display the directory.  DM2 shows all 4 of your programs as INT/VAR254.

Here are some screen shots. (Remember, I overwrote MILL34):

The ones with the very odd LRL values displayed on DM3's output produce I/O error 04 when trying to load them.  I suspect there's something odd with how the 99/4A is actually saving these.  MILL31, which I did not touch in any way, loads find on the 99/8.  MILL32 and MILL33 don't.  MILL34 does now because I fixed it by saving it in MERGE format on the 99/4A and then merged it on the 99/8 and saved it again.

I used your Mille Bourne game to test with.  

 

On the 99/4A in Extended BASIC, I exited the game that autostarted, and then did OLD DSK1.MILL34 followed by SAVE DSK1.MILMRG,MERGE

I then got into the 99/8 and MERGE DSK1.MILMRG - that seemed to work just fine.

SAVE DSK1.MILL34 saved it as INT/VAR 254 as expected.

could you upload the .dsk so I can play with it. I would like to know why those files show something other than 254? I never noticed that using TIDIR.

Sure.

 

I went back and repeated my test on Mame v0.216 and the behavior was the same, just for the record.

doesn't seem to work. unfortunately, neither does SAVE"DSK1.FILE",MERGE then on the ti99/8 MERGE"DSK1.FILE" it gives an error I/O error 4. doesn't matter size of file just gives error anyway. thing is, we don't know if TI ever intended to be able to transfer XB files seamlessly from the 99/4 to the 99/8?

@senior_falcon has a sub-program in TML that converts PROGRAM files to IV254 format, the opposite of what we want done. something like that might been needed and maybe it was TIs intention to release such? 

RXB 2015 documents:

SAVE command PAGE S1
-------------------------------------------------------------
Format SAVE DSK3.PRGM
SAVE DSK2.PRGM,IV254
Description
The SAVE command functions normally to save XB programs.
An additional freature is IV254 may be specified after the
SAVE command to convert to Internal Variable 254 format.
The IV254 format makes it much more easy to tell an XB
program from EA programs when cataloging a disk.
Internal Variable files do take up one sector more then
XB program format. It should be noted that XB programs
smaller then 3 sectors can not be saves in IV254 format.
Command
Saves to DISK 2 in XB program | >SAVE DSK2.TEST
image format TEST |
|
Saves to disk 3 in XB program | >sAVE DSK3.STUFF,IV254
Internal Variable 254 named |
STUFF |
|
Saves to WDS1 in dirctory EXB | >SAVE WDS1.EXB.RB,IV254
XB program Internal Variable |
254 named RB |
| |
Options
Allows better cataloging options for saving XB files.

RXB 2015 does not care about XB program size unless it is to small (i.e. less then 2 sectors in size).

You can save a 3 sector XB Program Image File as IV254 using:

SAVE DSK1.TEST,IV254 

 

Try RXB 2015 to see if it works?

You may be glad to hear that in the next MAME release (or the one after it; it may be too late for next Wednesday release) the TI-99/2 will offer an expansion slot and a 32K memory expansion. I never saw it in reality, but let's just assume that it could have existed.

 

mame64 ti99_232 -hexbus hx5102 -flop1 ti992testdssd.dsk -expport ram32k

 

I tested it with some BASIC programs, and it seems as if it actually works; I could load a TI BASIC program of 9 KiB size. There seem to be some issues with larger files, however: The screen space gets overwritten, you see some text on it. Note that you have to give it some time to parse the program; this takes up to 10 seconds and more, showing a blank screen. (I thought it crashed, but the cursor suddenly came back.)

interesting. I wonder if there was a switch to relocate the video ram when the memory was installed?

It could as well be a bug. You have to consider that we are probably the first people who add a memory expansion to the 99/2. 🙂

that's entirely possible too. BTW did you test it with both ROM versions?

In another topic area, there were files to upload to setup TIPI emulation.  Am I correct to assume that MAME can interface if QEMU is properly configured?

 

Assuming that to be the case, is the latest release of MAME able to use the TIPI or is it a matter of waiting for the next release?  If so, what is the command line argument to assign it a slot and is there a special string to tie it QEMU?

 

Also, I assume there is a binary needed for the TIPI eprom?  What is the filename needed for it to go into the zip file?

 

Trying to get a jumpstart on my questions I know I will have that I have not seen details posted anywhere.

Thanks.  I've got a few questions I will post in the js99er topic area assuming there is one.

@mizapf did ya'll do something with the hexbus? it now seems a little faster. earlier my i3 on the 99/8 would max to autoskip 10 and start skipping sound. but with this latest version it only goes to max 7 and rarely skips. much better.

Nope, I did not touch anything. I sometimes had an effect that MAME performed differently between builds (of the same source code); maybe the compiler creates better code from time to time. (This is not as unlikely as it sounds, since the compilers do heavy optimization, and sometimes building from clean yields better results.)

 

Maybe you had a CPU hog among your processes.
