TI-99/4a MiSTer Core

Recommended Posts

Hello,

I just got my MiSTer together and am struggling to get the TI core running. I guess there's a command to get the system roms combined into a single rom to use as the boot rom. I don't understand if this is a Windows DOS prompt or Linux or what. Any tips would be greatly appreciated.

I created a couple issues about this in the github repo... silence... 

 

The readme is worthless. I'm pretty sure most of what is in there has nothing to do with what is actually available on the MiSTer implementation. 

 

I enjoy the MiSTer for platforms where my retro hardware isn't as good as the FPGA version... not the case with my 4A.

For the TI99 core on MiSTer you can read my article on the TI99IUC site (it's in Italian...), updated to the latest core with Speech support. At the end of the article there is my MEGA Pack with all the needed TI99 stuff (all tested and working). There is a readme.txt file in English inside the .zip file. If you have additional questions just ask. 🙂

 

The article link is: http://www.ti99iuc.it/web/index.php?pageid=articoli_tech&artid=194#.X4_UlpJxeUk

 

Note that recently the TI99 core was ported from MiSTer to MIST/Mistica and SIDE FPGAs if someone has one of them.

Use this page https://github.com/GHPS/pyTIrom for initial help on the script to create system rom and carts. The instructions on the TI99 repository are related to Erik's code used for MiSTer version.

 

Anyway, I've already done all the conversion work and it's available on the link in the previous post. ;-)

Thanks! I got your files onto my MiSTer and the TI started up perfectly. :)

superfly doesn't work.. is this a bug in the fpga?  or a bad conversion of the cart?

It's working correctly starting from Core 20191020.

 

Previous versions:

some garbage on the player's selection screen (Use TI Computer Keys/How many Players?). The game starts, but when the superfly is captured it's not possible to continue to play.

 

I think you should also enable the speech, but this also on the real TI99 with FinalGROM. I'm not sure if in my package I have a "perfect" dump and/or if there are better versions available.

Have you noticed differences between the TI99 core and the real hw? What are your first impressions?

I see a disk controller rom can be included, but how do you configure the disks?

 

At the moment the disk is not supported. 😞 Only +32K and Speech, no disk or tape. There is an option for cpu overclock, useful for slow TI BASIC games in SSS format.

 

The most interesting feature is the ultra sharp resolution offered on a FullHD monitor. Add some scanlines for a complete retrò look. And you can use high quality arcade controllers or gamepads instead of the poor TI joysticks.

Since the MiSTer port of the 99/4A is based on my code I guess it starts to be the time to put together MiSTer myself too, have had the parts lying round a long time. I tried the MIST port a while ago, as I know how to operate MIST. I've been recently working on the icy99 version which is better (IMHO) structured but not done yet. I am planning to add TIPI support to icy99, as that should (?) be quick way of getting disk support.

This is a great new to have the original author of the TI99 core to return back to it and support the MiSTer and Mist ports! 🙂 We definitively need the disk (and tape?) support added to this great core.
