Asmusr Posted February 13, 2017 Share Posted February 13, 2017 I found some sheet music from Monkey Island 2 that I have been converting to a format playable by our music chip by entering it into the MOD2PSG2 tracker. I think the result is pretty good (although far from the original) so I decided to turn it into a slideshow demo with screenshots from the PC game. The music is played using Tursi's VGM tools, and the images have been converted using Tursi's Convert9918A tool. There are 3 versions of the demo: monkey8.bin is a 512K cartridge image for the original 9918A video chip. The image quality is pretty bad, but at least you have something to watch while listening to the music. The cart requires 32K RAM because the music player needs it, and I was too lazy to try to make it run on an unexpanded console. f18a-monkey8.bin is a 512K cartridge image for use with the F18A video chip. This is using Tursi's routine to display images with a new color palette for every scanline. The image quality is a lot better than for the 9918A, but there's still a long way to VGA. This runs fine in the latest version of Classic99, but JS99er.net is lagging (unless you have a faster computer than me) as is not recommended. The sound quality is best, of course, on real hardware. monkey.dsk contains an E/A#5 file with just the music and a single image.Try this if you want to hear the music, but cannot use one of the other options. We need The FinalGROM 99! I have also attached the music if you want to play around with the tracker. monkey8.bin f18a-monkey8.bin monkey.dsk music.zip 11 Quote Link to comment Share on other sites More sharing options...
Tursi Posted February 13, 2017 Share Posted February 13, 2017 (edited) The cart requires 32K RAM because the music player needs it, and I was too lazy to try to make it run on an unexpanded console. I have that mostly done... the 680Rock demo uses a version of the player that has all the data access abstracted to a function call so it could be used for bank switching or other locations like VDP with a simple function.

Omega-TI Posted February 13, 2017 Share Posted February 13, 2017 I downloaded the F18A version and burned it into a chip, it was fun to watch. 2 Quote Link to comment Share on other sites More sharing options...

budz2355 Posted February 14, 2017 Share Posted February 14, 2017 (edited) lol im dumb, I tried to stick the .bin version on my flashrom .. even though you mentioned above what it was. Finally when I looked at the file size, I knew I had to bust out the diskettes. TIMXT + Terminal Program on PC .... I have tons of OEM 3.5" floppies just waiting for something like this It's always fun firing up the disk drives! EDIT: Worked like a charm -- awesome and thank you for the fun! When I transferred this to disk (I only have 180K to play with on diskettes as I have the standard TI controller unmodded), I noticed it only took up 87 of the 718 sectors I had initialized on a new disk. Any chance the expanded version would fit on a disk? I have another 631 to play with Also ... I do have a horizon RAMdisk if more space is needed! Or is there someway I can 'unpack' that F18A .bin file and run it off a disk or ramdisk? Edited February 14, 2017 by budz2355 Quote Link to comment Share on other sites More sharing options...
+arcadeshopper Posted February 14, 2017 Share Posted February 14, 2017 awesome! burned and running on my f18 4/a Greg 2 Quote Link to comment Share on other sites More sharing options...
speccery Posted February 18, 2017 Share Posted February 18, 2017 This is a very nice demo indeed. Pictured here running of my F18A equipped TI-99/4A while using the Pipistrello FPGA as the "cartridge". Good job Asmusr! Now that I think about it, this probably also is the first time I'm running something F18 enhanced on my TI. The picture is from the non-F18 enhanced version, I tried the F18 version after that and it worked just as well. 1 Quote Link to comment Share on other sites More sharing options...
fabrice montupet Posted February 18, 2017 Share Posted February 18, 2017 Excellent sounds & musics ! I played the version using the (lovely) TMS9918A/29A and I find that graphics are good ! And I am sure that we can obtain even better pictures by reworking the drawings manually to adapt them within the TMS9918 colors proximity contraints. Thank you Rasmus and Tursi :-) Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted February 19, 2017 Share Posted February 19, 2017 Your demo brought back some great memories. I do not have a 512k cart handy, nor can the cart be used with a Geneve, so I have adapted the 512k ROM demo version to run from the Geneve in native OS mode. The demo loads the ROM data into available memory and pages it accordingly. I tested in both MESS and real hardware. Press ESCAPE to exit the demo. Thanks to Rasmus for the demo and for permission to release this adaptation. MonkeyIslandGeneve.dsk 4 Quote Link to comment Share on other sites More sharing options...

Asmusr Posted February 20, 2017 Author Share Posted February 20, 2017 I wonder if the F18A "one 16 color palette per scanline" data could be mapped to one of the 9938 modes? Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted February 20, 2017 Share Posted February 20, 2017 I wonder if the F18A "one 16 color palette per scanline" data could be mapped to one of the 9938 modes? The V9938 has a graphics mode (7) that might come close. The screen is 256x192, with one byte representing one dot. Each byte can be one of 256 colors, represented as [3 bit red|3 bit green|2 bit blue]. Each screen is approximately 50k bytes, so I guess one would write to the non-displayed screen, then change the screen table pointer when ready. How is the image and color data represented in the f18a rom? Quote Link to comment Share on other sites More sharing options...

How is the image and color data represented in the f18a rom? Patterns and colors are stored as for normal bitmap mode, but in addition each image has a block of 192 palettes (one for each horizontal pixel line) starting from bank 44 in the cart image. Each palette is 32 bytes long, holds 16 colors, and each color is represented by a word >0RGB where R, G, and B are 4 bits each. It seems like this should be quite easy to map to mode 7.

I might try that this weekend as I already have the f18a ROM file prepared. Would it be better to keep the most significant bits of each color? Red and Green will just lost one bit; blue will lose two.... Quote Link to comment Share on other sites More sharing options...

It will be interesting to see the results. Quote Link to comment Share on other sites More sharing options...

I might try some adjustments later in the week.. here is a MESS screenshot of the first pic. This is using the Geneve and V9938 in Graphics mode 7, with the F18A 12-bit palette converted to V9938 8-bit palette. 2 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted February 24, 2017 Share Posted February 24, 2017 (edited) Here is the same demo for the Geneve using the V9938 Graphics mode 7. The screens are built in alternating 64K banks in the background. When the timer expires for each screen, the pattern name table register is flipped to the already-built screen, allowing for the seamless transitions. I haven't done much with graphics modes in the past, so this was a good learning experience. The demo currently requires more CPU memory than a stock Geneve has available, so you'll need to use MESS or a Geneve with expanded RAM.

+mizapf Posted February 24, 2017 Share Posted February 24, 2017 (edited) To get it running, you have to use some special settings for MAME. 1. Since this is a 720k disk image, the default floppy drive will not work (40 tracks). You have to select a 3.5" drive for flop1. 2. You have to set the DIP switch on the HFDC controller to define your first drive to have 80 tracks (DIP switch settings in the OSD menu). 3. In GeneveOS you have to type in SETDSK 108. 4. In order to get more memory, do not forget to add the MEMEX. My command line looks like this: ./mame64 geneve -peb:slot3 memex \ -peb:slot8 hfdc \ -peb:slot8:hfdc:h1 generic -hard1 /home/michael/mame/disks/hd/scsi2.hd \ -peb:slot8:hfdc:f1 35dd -flop1 ti/andere/tesch/MonkeyIslandGeneve-V9938-720k.dsk (the \ are just continuations in the shell; you should write everything in one line.) Edit: The SETDSK is not required. Edited February 24, 2017 by mizapf 1 Quote Link to comment Share on other sites More sharing options...
+mizapf Posted February 25, 2017 Share Posted February 25, 2017 This looks really nice, but I guess it does not fully exploit the G7 mode. It's a port of the F18A graphics, isn't it? There are still many colored strokes, although every pixel may have an individual color. Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted February 25, 2017 Share Posted February 25, 2017 Awww maaaan! This line of discussion is getting me interested in Geneve's... but I simply cannot justify one. Quote Link to comment Share on other sites More sharing options...
